How might I specify in a specfile that I want to be able to use gcc

This is for CentOS 5.

if it's a flag to the compiler, then in the %configure line (assuming
you're using autoconf) then add

%ifarch x86_64
 %configure CXXFLAGS=-m32 CFLAGS=-m32

Upon reading this, I realize - I asked the wrong question! Your
answer is perfect, but I had already solved that problem. The problem
is, when I use -m32 gcc can't (on x86_64) find 32 bit support -
presumably due to missing packages. Which packages do I specify?
CentOS uses the (horrible, IMO) same-name-different-arch system which
causes no end of confusion and trouble. I want to specify, "I need
glibc but for 32 bit" but I don't seem to be able to specify it. The
.i386 glibc package doesn't even provide glibc(x86-32). Thoughts?
