--- Comment #5 from Matt Hargett <matt at use dot net> 2012-05-11 17:58:27 UTC --- It's not an IRIX-specific thing AFAICS, but rather that newer versions of cloog/ppl renamed the macro to avoid conflicts on IRIX. 4.6 still checks for the old macro name, which is no longer set. I have applied the patch locally to work around the issue and can verify it solved the problem for me. Let me know if there's anything else you'd like me to test/validate to get it back ported.
