#33 Irix build warnings - over 500 of them

[Jim Trainor]

The IRIX debug build generates over 500 warnings!!! The
release build may be even worse.

There are, however, only about six different types of
errors.

A bunch of the errors are for unused variables. Others
may be equally simple, and can be addressed by fixing
the code.

Other errors may simply need to be turned off.

I just recalled that I did not enter a comment about this...
better late then never:

Some of the warnings have been disabled by adding the
appropriate compile flags in pdefs-MipsIrix.mk. This was done
to cleanup the nightly build error logs (i.e as part of testing
the new scripts in AAF/build/tools).

Despite this, I think the best solution is to re-enable the
warnings and address the underlying issues with the code if
possible.
