I built gcc-4.3.5 with multilibs enabled (the default on Mac OS X)

../gcc-4.3.5/configure --enable-languages=c,pascal --enable-threads=posix --disable-nls 
--target=i386-apple-darwin9 --host=i386-apple-darwin9 --build=i386-apple-darwin9 
--prefix=/Developer/Pascal/gpc435u1 --disable-mapped-location

This does build and install 32-bit and 64-bit gcc.a and gpc.a. The 32-bit libs are installed in 
....../lib/gcc/i386-apple-darwin9/4.3.5, the 64-bit libs in a subfolder 

The gpc -m32 and -m64 now automatically work. Couldn't be better.
