I don't think anyone has successfully built flightgear with gcc on
irix.  I'm told that irix gcc has a number of bugs and that aren't
being fixed ... few irix users are gcc developers?  Erik Hofman is
able to build with the native irix compilers.  I wish I could help
more, but gcc on irix appears to have some significant problems. :-(

Any time you see "internal compiler error" you know you are looking at
a compiler bug.  However, with enough persistance and a lot of luck
you might be able to figure out which part of our code is tickling the
bug and then perhaps we could find a way to work around it in irix.
