Hi!

I've got a problem with "free" (or "xfree") routines - it's silly I know,
but they seems not to work...
I tried program listed below, and after freeing that "dummy" pointer,
free memory doesn't change... If anybody coud test it and help.

#include <stdio.h>
#include <dpmi.h>
#include <crt0.h>

int *dummy;

void main () {
         printf ("At start:                   physical mem %d   virtual mem %d\n",_go32_dpmi_remaining_physical_memory (),_go32_dpmi_remaining_virtual_memory ());
         dummy = (int*) malloc (100000);
         printf ("After allocating 100kbytes: physical mem %d   virtual mem %d\n",_go32_dpmi_remaining_physical_memory (),_go32_dpmi_remaining_virtual_memory ());
         free (dummy);
         printf ("After releasing 100kbytes:  physical mem %d   virtual mem %d\n",_go32_dpmi_remaining_physical_memory (),_go32_dpmi_remaining_virtual_memory ());
}
