Well, I presume that sometimes (often) those are used for limits of
something, and sometimes they're genuine integers.  Surely there's
something in GDB where a negative value would make sense.  I don't
like the idea of accepting "unlimited" for a quantity that isn't a
limit on anything.

Then, of course, there's aix-thread.c which is using zinteger for a boolean.
