apache-ant-1.9.3

>Description:

The following error occurs when attempting to build jogl on recent
versions of FreeBSD where clang is the default compiler and gcc is
not installed:

cx.build:
     [echo] Output lib name = gluegen-rt
    [mkdir] Created dir: /usr/ports/graphics/jogl/work/gluegen/build/obj
     [echo] Compiling src/native/unix/*.c
     [echo] user.dir=/usr/ports/graphics/jogl/work/jogl/make
       [cc] 1 total files to be compiled.

Stop.

The problems is that apache-ant has a hardwired set of C compilers
that it can use, and plain old cc is not one of them.  The default
is gcc.  This probably should be considered as a bug in apache-ant
...

Installing gcc from ports doesn't help because apache-ant is
specifically looking for gcc and not gcc46, or whatever version of
gcc we have installed.


>How-To-Repeat:

Attempt to build jogl on a machine without gcc in the $PATH.

>Fix:

The following patch to the graphics/jogl Makefile allows fakes
apache-ant into using our system C compiler.  On older FreeBSD
versions this is actually gcc, so it should be a NOP.  There doesn't
seem to be any issue with using clang in place of gcc on newer
versions of FreeBSD where it is the default compiler.  compiler.
