Well it's a bit off topic, but may be you can help me… Right now, I'm  
unable to compile FSF GCC 4.1 on Mac OS X 10.4, I just got this error :

checking for powerpc-apple-darwin8.6.0-gcc... /Users/qmathe/Desktop/ 
gccbuild/./gcc/xgcc -B/Users/qmathe/Desktop/gccbuild/./gcc/ -B/gcc41/

gcc41/powerpc-apple-darwin8.6.0/sys-include  -m64
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run  
C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
make[2]: *** [configure-target-libstdc++-v3] Error 1

In the config.log, the output is :

configure:2275: checking for correct version of gmp.h
configure:2288: gcc -c -g -O2   conftest.c 1>&5
configure:2278:17: error: gmp.h: No such file or directory
configure: In function 'main':

Then I suppose I have to install libgmp (because it isn't part of Mac  
OS X by default, right ?), but it looks weird in my opinion taking in  
account it has never been the case in the past iirc.

Here are my configure flags : '--prefix=/gcc41 --enable-languages=c,c+ 
+,objc,obj-c++ --enable-threads=posix'

Thanks,
Quentin.
