there's a function in _go32 [actually 2 functions, one is a macro i think, tho]

something like:
_go32_get_info_about_my_computer(bunch of vars)
and
_go32_get_free_physical_memory_so_i_dont_run_out()
_go32_get_free_virtual_memory_so_i_dont_run_out()

[please see the go32 headers or docs in the info tree for the correct names.  i
don't have them available on this computer or id give you the correct ones]

only difference seems to be that under borland when you do a coreleft you get
something like:

48325  or _maybe_ 425993 if compiled in large or something

and w/ the same program under djgpp you get

31425876

:)
[at least my version of borland c doesn't have an extender.  do the latest
releases?]
