When run under WIN95, DJGPP uses the DPMI that Windows provides instead
of CWSDPMI.  If you have enabled virtual memory under Win95, then your progs
will get it.  If you haven't, they won't.  To see exactly how much memory you
have
available, simply run 'go32-v2' from a DOS shell.  Under Windows, it reports
the
sum of real and virtual memory as one lump sum under 'physical memory'.
