+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The C preprocessor, often known as \fIcpp\fR, is a \fImacro processor\fR
+that is used automatically by the C compiler to transform your program
+before compilation. It is called a macro processor because it allows
+you to define \fImacros\fR, which are brief abbreviations for longer
+constructs.
+.PP
+The C preprocessor is intended to be used only with C and \*(C+ source
+code. In the past, it has been abused as a general text processor. It
+will choke on input which does not obey C's lexical rules. For
+example, apostrophes will be interpreted as the beginning of character
+constants, and cause errors. Also, you cannot rely on it preserving
+characteristics of the input which are not significant to C\-family
+languages. If a Makefile is preprocessed, all the hard tabs will be
+removed, and the Makefile will not work.
+.PP
+Having said that, you can often get away with using cpp on things which
+are not C. Other Algol-ish programming languages are often safe
+(Pascal, Ada, etc.) So is assembly, with caution. \fB\-traditional\-cpp\fR
+mode preserves more white space, and is otherwise more permissive. Many
+of the problems can be avoided by writing C or \*(C+ style comments
+instead of native language comments, and keeping macros simple.
+.PP
+Wherever possible, you should use a preprocessor geared to the language
+you are writing in. Modern versions of the \s-1GNU\s0 assembler have macro
+facilities. Most high level programming languages have their own
+conditional compilation and inclusion mechanism. If all else fails,
+try a true general text processor, such as \s-1GNU\s0 M4.
+.PP
+C preprocessors vary in some details. This manual discusses the \s-1GNU\s0 C
+preprocessor, which provides a small superset of the features of \s-1ISO\s0
+Standard C. In its default mode, the \s-1GNU\s0 C preprocessor does not do a
+few things required by the standard. These are features which are
+rarely, if ever, used, and may cause surprising changes to the meaning
+of a program which does not expect them. To get strict \s-1ISO\s0 Standard C,
+you should use the \fB\-std=c89\fR or \fB\-std=c99\fR options, depending
+on which version of the standard you want. To get all the mandatory
+diagnostics, you must also use \fB\-pedantic\fR.
+.PP
+This manual describes the behavior of the \s-1ISO\s0 preprocessor. To
+minimize gratuitous differences, where the \s-1ISO\s0 preprocessor's
+behavior does not conflict with traditional semantics, the
+traditional preprocessor should behave the same way. The various
+differences that do exist are detailed in the section \fBTraditional
+Mode\fR.
+.PP
+For clarity, unless noted otherwise, references to \fB\s-1CPP\s0\fR in this
+manual refer to \s-1GNU\s0 \s-1CPP\s0.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+The C preprocessor expects two file names as arguments, \fIinfile\fR and
+\&\fIoutfile\fR. The preprocessor reads \fIinfile\fR together with any
+other files it specifies with \fB#include\fR. All the output generated
+by the combined input files is written in \fIoutfile\fR.
+.PP
+Either \fIinfile\fR or \fIoutfile\fR may be \fB\-\fR, which as
+\&\fIinfile\fR means to read from standard input and as \fIoutfile\fR
+means to write to standard output. Also, if either file is omitted, it
+means the same as if \fB\-\fR had been specified for that file.
+.PP
+Unless otherwise noted, or the option ends in \fB=\fR, all options
+which take an argument may have that argument appear either immediately
+after the option, or with a space between option and argument:
+\&\fB\-Ifoo\fR and \fB\-I foo\fR have the same effect.
+.PP
+Many options have multi-letter names; therefore multiple single-letter
+options may \fInot\fR be grouped: \fB\-dM\fR is very different from
+\&\fB\-d\ \-M\fR.
+.IP "\fB\-D\fR \fIname\fR" 4
+.IX Item "-D name"
+Predefine \fIname\fR as a macro, with definition \f(CW1\fR.
+.IP "\fB\-D\fR \fIname\fR\fB=\fR\fIdefinition\fR" 4
+.IX Item "-D name=definition"
+The contents of \fIdefinition\fR are tokenized and processed as if
+they appeared during translation phase three in a \fB#define\fR
+directive. In particular, the definition will be truncated by
+embedded newline characters.
+.Sp
+If you are invoking the preprocessor from a shell or shell-like
+program you may need to use the shell's quoting syntax to protect
+characters such as spaces that have a meaning in the shell syntax.
+.Sp
+If you wish to define a function-like macro on the command line, write
+its argument list with surrounding parentheses before the equals sign
+(if any). Parentheses are meaningful to most shells, so you will need
+to quote the option. With \fBsh\fR and \fBcsh\fR,
+\&\fB\-D'\fR\fIname\fR\fB(\fR\fIargs...\fR\fB)=\fR\fIdefinition\fR\fB'\fR works.
+.Sp
+\&\fB\-D\fR and \fB\-U\fR options are processed in the order they
+are given on the command line. All \fB\-imacros\fR \fIfile\fR and
+\&\fB\-include\fR \fIfile\fR options are processed after all
+\&\fB\-D\fR and \fB\-U\fR options.
+.IP "\fB\-U\fR \fIname\fR" 4
+.IX Item "-U name"
+Cancel any previous definition of \fIname\fR, either built in or
+provided with a \fB\-D\fR option.
+.IP "\fB\-undef\fR" 4
+.IX Item "-undef"
+Do not predefine any system-specific or GCC-specific macros. The
+standard predefined macros remain defined.
+.IP "\fB\-I\fR \fIdir\fR" 4
+.IX Item "-I dir"
+Add the directory \fIdir\fR to the list of directories to be searched
+for header files.
+.Sp
+Directories named by \fB\-I\fR are searched before the standard
+system include directories. If the directory \fIdir\fR is a standard
+system include directory, the option is ignored to ensure that the
+default search order for system directories and the special treatment
+of system headers are not defeated
+\&.
+.IP "\fB\-o\fR \fIfile\fR" 4
+.IX Item "-o file"
+Write output to \fIfile\fR. This is the same as specifying \fIfile\fR
+as the second non-option argument to \fBcpp\fR. \fBgcc\fR has a
+different interpretation of a second non-option argument, so you must
+use \fB\-o\fR to specify the output file.
+.IP "\fB\-Wall\fR" 4
+.IX Item "-Wall"
+Turns on all optional warnings which are desirable for normal code.
+At present this is \fB\-Wcomment\fR, \fB\-Wtrigraphs\fR,
+\&\fB\-Wmultichar\fR and a warning about integer promotion causing a
+change of sign in \f(CW\*(C`#if\*(C'\fR expressions. Note that many of the
+preprocessor's warnings are on by default and have no options to
+control them.
+.IP "\fB\-Wcomment\fR" 4
+.IX Item "-Wcomment"
+.PD 0
+.IP "\fB\-Wcomments\fR" 4
+.IX Item "-Wcomments"
+.PD
+Warn whenever a comment-start sequence \fB/*\fR appears in a \fB/*\fR
+comment, or whenever a backslash-newline appears in a \fB//\fR comment.
+(Both forms have the same effect.)
+.IP "\fB\-Wtrigraphs\fR" 4
+.IX Item "-Wtrigraphs"
+Most trigraphs in comments cannot affect the meaning of the program.
+However, a trigraph that would form an escaped newline (\fB??/\fR at
+the end of a line) can, by changing where the comment begins or ends.
+Therefore, only trigraphs that would form escaped newlines produce
+warnings inside a comment.
+.Sp
+This option is implied by \fB\-Wall\fR. If \fB\-Wall\fR is not
+given, this option is still enabled unless trigraphs are enabled. To
+get trigraph conversion without warnings, but get the other
+\&\fB\-Wall\fR warnings, use \fB\-trigraphs \-Wall \-Wno\-trigraphs\fR.
+.IP "\fB\-Wtraditional\fR" 4
+.IX Item "-Wtraditional"
+Warn about certain constructs that behave differently in traditional and
+\&\s-1ISO\s0 C. Also warn about \s-1ISO\s0 C constructs that have no traditional C
+equivalent, and problematic constructs which should be avoided.
+.IP "\fB\-Wimport\fR" 4
+.IX Item "-Wimport"
+Warn the first time \fB#import\fR is used.
+.IP "\fB\-Wundef\fR" 4
+.IX Item "-Wundef"
+Warn whenever an identifier which is not a macro is encountered in an
+\&\fB#if\fR directive, outside of \fBdefined\fR. Such identifiers are
+replaced with zero.
+.IP "\fB\-Wunused\-macros\fR" 4
+.IX Item "-Wunused-macros"
+Warn about macros defined in the main file that are unused. A macro
+is \fIused\fR if it is expanded or tested for existence at least once.
+The preprocessor will also warn if the macro has not been used at the
+time it is redefined or undefined.
+.Sp
+Built-in macros, macros defined on the command line, and macros
+defined in include files are not warned about.
+.Sp
+\&\fINote:\fR If a macro is actually used, but only used in skipped
+conditional blocks, then \s-1CPP\s0 will report it as unused. To avoid the
+warning in such a case, you might improve the scope of the macro's
+definition by, for example, moving it into the first skipped block.
+Alternatively, you could provide a dummy use with something like:
+.Sp
+.Vb 2
+\& #if defined the_macro_causing_the_warning
+\& #endif
+.Ve
+.IP "\fB\-Wendif\-labels\fR" 4
+.IX Item "-Wendif-labels"
+Warn whenever an \fB#else\fR or an \fB#endif\fR are followed by text.
+This usually happens in code of the form
+.Sp
+.Vb 5
+\& #if FOO
+\& ...
+\& #else FOO
+\& ...
+\& #endif FOO
+.Ve
+.Sp
+The second and third \f(CW\*(C`FOO\*(C'\fR should be in comments, but often are not
+in older programs. This warning is on by default.
+.IP "\fB\-Werror\fR" 4
+.IX Item "-Werror"
+Make all warnings into hard errors. Source code which triggers warnings
+will be rejected.
+.IP "\fB\-Wsystem\-headers\fR" 4
+.IX Item "-Wsystem-headers"
+Issue warnings for code in system headers. These are normally unhelpful
+in finding bugs in your own code, therefore suppressed. If you are
+responsible for the system library, you may want to see them.
+.IP "\fB\-w\fR" 4
+.IX Item "-w"
+Suppress all warnings, including those which \s-1GNU\s0 \s-1CPP\s0 issues by default.
+.IP "\fB\-pedantic\fR" 4
+.IX Item "-pedantic"
+Issue all the mandatory diagnostics listed in the C standard. Some of
+them are left out by default, since they trigger frequently on harmless
+code.
+.IP "\fB\-pedantic\-errors\fR" 4
+.IX Item "-pedantic-errors"
+Issue all the mandatory diagnostics, and make all mandatory diagnostics
+into errors. This includes mandatory diagnostics that \s-1GCC\s0 issues
+without \fB\-pedantic\fR but treats as warnings.
+.IP "\fB\-M\fR" 4
+.IX Item "-M"
+Instead of outputting the result of preprocessing, output a rule
+suitable for \fBmake\fR describing the dependencies of the main
+source file. The preprocessor outputs one \fBmake\fR rule containing
+the object file name for that source file, a colon, and the names of all
+the included files, including those coming from \fB\-include\fR or
+\&\fB\-imacros\fR command line options.
+.Sp
+Unless specified explicitly (with \fB\-MT\fR or \fB\-MQ\fR), the
+object file name consists of the basename of the source file with any
+suffix replaced with object file suffix. If there are many included
+files then the rule is split into several lines using \fB\e\fR\-newline.
+The rule has no commands.
+.Sp
+This option does not suppress the preprocessor's debug output, such as
+\&\fB\-dM\fR. To avoid mixing such debug output with the dependency
+rules you should explicitly specify the dependency output file with
+\&\fB\-MF\fR, or use an environment variable like
+\&\fB\s-1DEPENDENCIES_OUTPUT\s0\fR. Debug output
+will still be sent to the regular output stream as normal.
+.Sp
+Passing \fB\-M\fR to the driver implies \fB\-E\fR, and suppresses
+warnings with an implicit \fB\-w\fR.
+.IP "\fB\-MM\fR" 4
+.IX Item "-MM"
+Like \fB\-M\fR but do not mention header files that are found in
+system header directories, nor header files that are included,
+directly or indirectly, from such a header.
+.Sp
+This implies that the choice of angle brackets or double quotes in an
+\&\fB#include\fR directive does not in itself determine whether that
+header will appear in \fB\-MM\fR dependency output. This is a
+slight change in semantics from \s-1GCC\s0 versions 3.0 and earlier.
+.IP "\fB\-MF\fR \fIfile\fR" 4
+.IX Item "-MF file"
+When used with \fB\-M\fR or \fB\-MM\fR, specifies a
+file to write the dependencies to. If no \fB\-MF\fR switch is given
+the preprocessor sends the rules to the same place it would have sent
+preprocessed output.
+.Sp
+When used with the driver options \fB\-MD\fR or \fB\-MMD\fR,
+\&\fB\-MF\fR overrides the default dependency output file.
+.IP "\fB\-MG\fR" 4
+.IX Item "-MG"
+In conjunction with an option such as \fB\-M\fR requesting
+dependency generation, \fB\-MG\fR assumes missing header files are
+generated files and adds them to the dependency list without raising
+an error. The dependency filename is taken directly from the
+\&\f(CW\*(C`#include\*(C'\fR directive without prepending any path. \fB\-MG\fR
+also suppresses preprocessed output, as a missing header file renders
+this useless.
+.Sp
+This feature is used in automatic updating of makefiles.
+.IP "\fB\-MP\fR" 4
+.IX Item "-MP"
+This option instructs \s-1CPP\s0 to add a phony target for each dependency
+other than the main file, causing each to depend on nothing. These
+dummy rules work around errors \fBmake\fR gives if you remove header
+files without updating the \fIMakefile\fR to match.
+.Sp
+This is typical output:
+.Sp
+.Vb 1
+\& test.o: test.c test.h
+.Ve
+.Sp
+.Vb 1
+\& test.h:
+.Ve
+.IP "\fB\-MT\fR \fItarget\fR" 4
+.IX Item "-MT target"
+Change the target of the rule emitted by dependency generation. By
+default \s-1CPP\s0 takes the name of the main input file, including any path,
+deletes any file suffix such as \fB.c\fR, and appends the platform's
+usual object suffix. The result is the target.
+.Sp
+An \fB\-MT\fR option will set the target to be exactly the string you
+specify. If you want multiple targets, you can specify them as a single
+argument to \fB\-MT\fR, or use multiple \fB\-MT\fR options.
+.Sp
+For example, \fB\-MT\ '$(objpfx)foo.o'\fR might give
+.Sp
+.Vb 1
+\& $(objpfx)foo.o: foo.c
+.Ve
+.IP "\fB\-MQ\fR \fItarget\fR" 4

+.IP "\fB\-MD\fR" 4
+.IX Item "-MD"
+\&\fB\-MD\fR is equivalent to \fB\-M \-MF\fR \fIfile\fR, except that
+\&\fB\-E\fR is not implied. The driver determines \fIfile\fR based on
+whether an \fB\-o\fR option is given. If it is, the driver uses its
+argument but with a suffix of \fI.d\fR, otherwise it take the
+basename of the input file and applies a \fI.d\fR suffix.
+.Sp
+If \fB\-MD\fR is used in conjunction with \fB\-E\fR, any
+\&\fB\-o\fR switch is understood to specify the dependency output file, but if used without \fB\-E\fR, each \fB\-o\fR
+is understood to specify a target object file.
+.Sp
+Since \fB\-E\fR is not implied, \fB\-MD\fR can be used to generate
+a dependency output file as a side-effect of the compilation process.

+.PD
+Specify the source language: C, \*(C+, or assembly. This has nothing
+to do with standards conformance or extensions; it merely selects which

+deduce the language from the extension of the source file: \&\fB.c\fR,
+\fB.cc\fR, or \fB.S\fR. Some other common extensions for \*(C+ and
+assembly are also recognized. If cpp does not recognize the extension,
+it will treat the file as C; this is the most generic mode.
+.Sp

+.IP "\fB\-fpreprocessed\fR" 4
+.IX Item "-fpreprocessed"
+Indicate to the preprocessor that the input file has already been
+preprocessed. This suppresses things like macro expansion, trigraph
+conversion, escaped newline splicing, and processing of most directives.
+The preprocessor still recognizes and removes comments, so that you can
+pass a file preprocessed with \fB\-C\fR to the compiler without

+\&\fB\-fpreprocessed\fR is implicit if the input file has one of the

+corresponds to the width of \f(CW\*(C`wchar_t\*(C'\fR. As with
+\&\fB\-fexec\-charset\fR, \fIcharset\fR can be any encoding supported
+by the system's \f(CW\*(C`iconv\*(C'\fR library routine; however, you will have
+problems with encodings that do not fit exactly in \f(CW\*(C`wchar_t\*(C'\fR.
+.IP "\fB\-finput\-charset=\fR\fIcharset\fR" 4
+.IX Item "-finput-charset=charset"
+Set the input character set, used for translation from the character
+set of the input file to the source character set used by \s-1GCC\s0. If the
+locale does not specify, or \s-1GCC\s0 cannot get this information from the
+locale, the default is \s-1UTF\-8\s0. This can be overridden by either the locale
+or this command line option. Currently the command line option takes
+precedence if there's a conflict. \fIcharset\fR can be any encoding
+supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine.

+Enable generation of linemarkers in the preprocessor output that will

+emit, after the initial linemarker, a second linemarker with the
+current working directory followed by two slashes. \s-1GCC\s0 will use this
+directory, when it's present in the preprocessed input, as the
+directory emitted as the current working directory in some debugging
+information formats. This option is implicitly enabled if debugging
+information is enabled, but this can be inhibited with the negated
+form \fB\-fno\-working\-directory\fR. If the \fB\-P\fR flag is
