Strange. But I have to admit that I did my test on an IRIX 6.3 box, so the
comparison is not fair.

The MipsPRO C error messages are at least "a bit cryptic", and that
certainly is one of the reasons why I use gcc on IRIX (although MipsPRO is
faster): you can actually understand its error messages and warnings. But
then again: I've seen compilers with even worse error messages like
"foo.c: error 42".
