it's worth noting a 'cleaner' way to do this than messing up your main
system with 32-bit packages is to use mock: you can use mock -r
fedora-16-i386 --shell to give yourself interactive access to a nice
clean 32-bit buildroot, then install all the devel packages and
compilers you need, and build your code. Might not be what you want, but
I thought it was worth mentioning.
