GNU Emacs 24.3.94 successfully builds under Solaris 10 (sparc) and AIX 7.1 
(POWER) but does not build under IRIX 6.5 (MIPS) with GCC 3.4.6.  The build log 
is attached.

We were planning to drop support for IRIX in GNU Emacs 25 anyway, as SGI itself 
dropped support for IRIX last year, so perhaps the simplest fix would be to add 
a NEWS item that IRIX is no longer supported.

Here's what 'report-emacs-bug' says when I run temacs:
