That's a lot of fancy. I wish I just new what the flags were, as it doesn't build on Snow Leopard for me.
I've always build mine with:
./configure --with-ns
make -j 4 bootstrap
I think I'm going to have to figure out how to build with -m32 so that it works on versions before 10.6. I haven't looked into it but I suspect you can "lipo" the 32 and the 64 bit executables together like you can with PowerPC and Intel and so that might be an option too.
