3.1 compilation woes on Mac OS X

[Aurelien]

Hi,

I've tried to compile gcc 3.1 on Mac OS X, configuring with 
--prefix=/usr/local/gcc --enable-languages=c,c++,objc

During the configuration process, I've found the following intriguing, 
in order of appearance:

1) Configuring for a powerpc-apple-darwin1.3.3 host.
*** This configuration is not supported in the following subdirectories;
     target-libffi target-boehm-gc target-zlib target-libjava 
target-libchill target-libf2c zlib fastjar
2) checking for iconv... no, consider installing GNU libiconv
3) Configuring etc...
No configuration information in etc

Is any of the above messages likely to prevent the compiler to be 
compiled with "make bootstrap", with the following error:

../xgcc -B./ -B/usr/local/gcc/powerpc-apple-darwin1.3.3/bin/ -isystem 
/usr/local/gcc/powerpc-apple-darwin1.3.3/include -O2   -DIN_GCC    -W 
-Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem 
../include   -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I.

make[2]: *** [stmp-multilib] Error 2
make[1]: *** [stage1_build] Error 2
make: *** [bootstrap] Error 2

???

Any clues ?
