I've been doing some C programming on the IBM PC lately have have run into
a snag. Unsigned longs do not seem to be supported. I've changed into the
HUGE mode to get 32 bit int's, but any variables of type unsigned long which
have the high bit set (i.e. would be negative if just longs) do not do the
right thing when used with ">>", "/", or "%". I've reported this problem
to Borland, but have not gotten a patch/work-around yet.
Has anyone here run into this problem, and found a workaround other that
coding subroutines to do it the right way?

This is the original poster. I recieved mail saying that their versions
of TurboC v2.0 worked correctly. I was baseing my claim on differences
in output from my programs on different platforms, unfortunately I
reported the wrong problem (GIGO, damn CR/LF stupidity) compounded by the
fact that the Turbo-Debugger's Inspect function does not work in the same
way of the TurboC Inspect function. It's the debugger that treats
unsigned longs as signed longs. Sorry for jumping to the wrong
conclusion, now back into my hole....
