I think that GDB on mips-irix has been in dire need of attention.
It's something I have on my list and I hope to get to it by the end
of the year, but my hopes often get overridden by more urgent issues...
The release that AdaCore uses in its product is GDB 5.3 (very old now,
I know).

I didn't see this problem when I tried to build on this platform.
But I was using the CVS HEAD, so either this is already fixed there,
or we're using different compiler versions (mine is based on 4.1).

Please send in the details. There was some talk about adding GNU make
as a requirement to build GDB, but this may not happen.
