FX,
I normally build the i686 native FSF gcc compiler under i386 fink which
uses compiler wrappers to force the 32-bit code generation from the system
compiler. However...
CC='gcc -m32' CXX='g++ -m32' ./configure -with-arch=nocona --with-tune=generic --build=i686-apple-darwin10 --host=i686-apple-darwin10 --target=i686-apple-darwin10
should work. You also could use just...
CC='gcc -m32' CXX='g++ -m32' ./configure -with-arch=nocona --with-tune=generic
since config.guess would detect the target as i386-apple-darwin10 but would likely
be less optimized.
