[RFA] port simple gdb.threads/schedlock.c test fix to branch

[Michael Elizabeth Chastain <mec@shout.net>]

I would like to port this fix from mainline to 5.3 branch:

  http://sources.redhat.com/ml/gdb-patches/2002-10/msg00454.html

  2002-10-22  Daniel Jacobowitz  <drow@mvista.com>

        * gdb.threads/schedlock.c (args): Make unsigned.

Note that this is a test program fix, not a gdb fix.

This fix improves the results from schedlock.exp, making them more
accurate and reproducible.  Right now, I'm getting random failures
in schedlock.exp on the branch, and it takes work to determine that
the failures really are random and not correlated with different
versions of gcc and binutils.

I tested this patch in my test bed with 66 different configurations
(on the 5.3 branch) and it works fine.  And, of course, it's been
working in mainline just fine.

I think this is obvious, but since I've been away for a while,
I just want to check first.

Okay to apply to the 5.3 branch?
