There is a difference between IRIX and the others. IRIX supports up to 3 ABIs named
o32, n32 and 64 at once.

Befor someone starts asking.. n32 is the new 32bit ABI which is now used since serveral years. The
directory named  usr/lib for o32, usr/lib32 for n32 and at least usr/lib64.  Official freeware
software pakages for IRIX from their freeware.sgi.com page have all modification to match to this
layout. For php they used a patched configure with a var called $ABILIB which is similar to the suse
patch or so

Our AMD64 boxes which are runing a 64bit gentoo-linux have a usr/lib64 .... but the dudes have also
a /usr/lib which is a symlink to the lib64 directory. I cant believe that they have made any big
changes to all of the configures.

How does it looks to other OSs like Tru64 and Solaris?
