if (blah) ...

Hi all,

Noticed an odd thing happening with some of my code (and some stock) since
moving servers.
The common construct:
if (blah)
   do this;
   do something else;

Doesn't seem to work correctly.
Occasionally it will do "this" instead of "something else" even if "blah"
is negative or null.

I've been fixing up bits of code as I notice them, using:

if (blah != NULL)
   do this;
   do something else;

or if (blah > 0), depending on what type of variable blah is.

This has caused the most problems in mobact.c, apparently, but was also
crashing the mud in do_disconnect and a few other places.

Anyone know why this would suddenly have started happening? Is it to do
with versions of compilers, operating systems, or something else entirely?
