If you have a clang built FreeBSD-current, then it is no
longer possible to *bootstrap* gcc-4.6.x, gcc-4.7.x, nor
the upcoming gcc-4.8.0.  AFAICT, the problem is related
to /usr/bin/cpp.  I haven't tried earlier versions of
gcc.

I have built the lang/gcc47 and lang/gcc48 ports just now, and they
compiled without any issues.  What is the exact error you have been
getting?

I think there must be a common problem you and Oliver have in your build
environment, most likely non-default CFLAGS.  What happens if you remove
make.conf and src.conf, do the gcc ports then build successfully?

FWIW,

Yesterday, I built lang/gcc on a 10.0-CURRENT amd64 svn 247236,
WITH_CLANG_IS_CC, and got the same error than the OP.

NO non-default CFLAGS.

The build succeeded with USE_GCC=any

I tried to restore the bootstrap phase by partially reverting r302041, and the
build errored with clang AND with the base gcc, at another place (some double
definitions building libcpp).
