FWIW, I can build R12B-3 fine on CentOS 5.2 / x86_64.
But if I force a 32-bit build (by setting CC when configuring)
then I get the same error you got.

Looks like a bug in CentOS, maybe inherited from RHEL5.

I did notice that the keyutils-libs-devel rpm only existed as
an i386 rpm, whereas all other openssl/krb5 stuff existed as
both i386 and x86_64 rpms. That may or may not be relevant to
this issue.
