Build problem with gcc 3.4 on Mac OS X


Hello,
I'm getting a weird error with the build process under Mac OS X Panther while configuring gcc 3.4.


$ cd gcc-3.4.0
$ mkdir BUILD
$ cd BUILD
$ ../configure --prefix=/usr --program-suffix="-3.4" --with-cpu=ppc --enable-altivec ppc --target=i686
...
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
$ grep cpp gcc/config.log
/Users/davang/gcc-3.4.0/gcc/configure: line 1: /lib/cpp: No such file or directory
configure:2814: /lib/cpp conftest.c
...


Ok, I've no /lib/cpp binary!
$ CPP="/usr/bin/cpp" make
...
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
$ grep cpp gcc/config.log
configure:2896: result: /usr/bin/cpp3
configure:2921: /usr/bin/cpp3 conftest.c
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
configure:2921: /usr/bin/cpp3 conftest.c
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
configure:2995: error: C preprocessor "/usr/bin/cpp3" fails sanity check
ac_cv_env_CPP_value=/usr/bin/cpp3
ac_cv_prog_CPP=/usr/bin/cpp3
CPP='/usr/bin/cpp3'

So I've tried to turning off smart processing:
$ CPP="/usr/bin/cpp" CPPFLAGS="-no-cpp-precomp" make
...
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
$ grep -i cpp gcc/config.log

CPP='/usr/bin/cpp'
CPPFLAGS='-no-cpp-precomp'
cpp_install_dir=''
$ cpp --version
cpp --version

Thanks for any input.
