Building on SGI with IRIX 6.2

[Reiner Suikat]

Hello,

I'm trying to build Sourcenav 4.5.2 on an SGI Indigo 2 workstation running
IRIX 6.2. I had no success using SGI's compiler, but did get a lot farther
with gcc (version 2.8.1).

Unfortunately, it doesn't work all the way, it breaks here:

Any idea? Do I need a more recent version of gcc? Even better, is there a
binary for SGI available somewhere?

Thanks
