   I want to recursivesly do makes...

   It seems each invocation takes over 100k out of my conventional memory,
   so after 3 levels I'm "out of space to exec"


The Gnuish make (and swalib) was mentioned.  The `problem' with 
these is that swalib is MicroSoft C specific and quite heavily
so.  Otherwise, I believe this to be a very good library -- it
swaps to XMS or disk.

My port of Gnu Make 3,71 (gmake371.zip out there) takes up around
30K at exec time.  If that's not good enough you should be able
to hack the swapping routine and get down to 1K + space for 
environment.  A couple of hours, max.  I just never needed it.
[Incidently, this swapping routine could easily be merged with
go32 if anybody wants to.]

The reason that Djgpp 2.0 will not have a memory-eating exec is
that there will be no go32.  The first invocation of a Djgpp
program will make sure that a Dpmi host is available.  The next
will just use it.  In other words, there is no need to blame
Qdpmi for eating memory.
