Hi Alexander,

compiling GCC 4.2 natively as part of the sparc64 world apparently
is broken due to some file not being generated as expected. This
also happens with a post symbol versioning world installed, cross-
compiling it works fine though. Another variant I see is
(the full log is at http://people.freebsd.org/~marius/build.txt):
cc -O2 -fno-strict-aliasing -pipe -DIN_GCC -DHAVE_CONFIG_H -DPREFIX=\"/usr/obj/usr/src/tmp/usr\" -I/usr/obj/usr/src/tmp/usr/src/gnu/usr.bin/cc/cc_int/../cc_tools -I/usr/src/gnu/usr.bin/cc/cc_int/../cc_tools -I/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc -I/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc/config -I/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/include -I/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/libcpp/include -I/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/libdecnumber  -I/usr/obj/usr/src/tmp/legacy/usr/include -c /usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc/c-lex.c /usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc/c-lex.c: In function 'c_lex_with_flags':

Do you have an idea what's causing this? I remeber one of your
earlier GCC 4.1 snapshots exhibiting similar problems, the next
one worked fine though.
