I took some time to complete the IRIX port yesterday. It's basically the Linux port with only one line worth of changes. That made me very very happy.

For everyone at home keeping score, Overkill now runs on the following:
Operating Systems: Windows, Linux, IRIX.
Processors: Intel x86, MIPS III/IV 32bit
Future platforms will probably include Mac OS-X, Solaris, and FreeBSD.
I'm also looking into getting at least one 64bit system to test on to make sure that there are no 64bit issues. This should insure that we have Overkill for a long time to come.
