IRIX still relevant?

Caolàn just filed me 
<http://qa.openoffice.org/issues/show_bug.cgi?id=106774> "sal: irix code 
writes past end of buffer" which made me wonder whether there is an 
active IRIX port at all, or whether the better fix for that issue would 
not be to rather remove all traces of IRIX from the code base.

<http://porting.openoffice.org/> lists IRIX as a regular port, but 
<http://porting.openoffice.org/irix/index.html> seems rather dated (it 
offers a download of OOo 1.0.3, and "was last updated on May 7th, [...] 
2003").

Opinions, anyone?
