Hi, folks.

We are having a little trouble with a problem I don't dare calling a bug.
Using a malloc()-call in small model with a variable size produces bizzare
results, if the requested memory size is not an unsigned value. For example

  cp = (char*)malloc(70000);

does not return NULL as you might expect, but reserves about 4500 bytes
of memory and returns a pointer to this area. Obviously the value is
casted to unsigned implicitly. We are now looking for an elegant(!) way
to produce proper results, for example replacing the malloc-routine in
CS.LIB (module NearHeap). If anybody out there has already solved this
problem, please E-mail me.
Solutions for C are not needed (we managed that), but only such for
C++ (TC++ 1.01).

Thanx, a lot
                           Joscho
