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?
