Subject: ld and GCC-RM

GCC-RM is just a real-mode version of GCC.  This is not likely to help
with memory problems, as GCC will take up ~130KB due to the GO32 stub,
but as far as I know GCC-RM does not swap itself out.  (At least the
difference was not enough to fix *my* make+GCC+compiler runs out of
memory woes.)  It is available as GCC257RM.ZIP (or something very like
that) at all the usual places if you want to try it anyway.
    The problem you're running into seems very unlikely to be that
kind of problem, however.  Out of memory usually seems to give either
a "GO32 can't find room to load" message, or a system crash (the
latter happens when you have exactly the right amount of space left,
and is quite rare in my experience).
    What seems to be happening is that your command line is getting
truncated somehow.  This is presumably due to some problem in passing
long arguments between GCC and the loader.  Why this should happen I'm
not sure; I know that I've had problems although everybody tells me I
shouldn't.  I think it may be that although *GCC* knows how to pass
those args to DJGPP compiler suite programs, *Make* doesn't.  (A
possible cause of this is if the makefile is written so that Make uses
the shell to call gcc rather than system("gcc arguments"), which knows
how to pass long arguments.)  A possible solution is to get Morten
Welinder's GMake 3.70, available at Garbo (I think that's
garbo.uwasa.fi) in a programming tools directory (possibly
something/msdos/programming).  It's not in with the C stuff or with
GNUish project stuff.  You may just have to break down and use a
response file.  (This is most reliable in my experience.)
    Oops, after rereading your message, I *think* you've already tried
the response file method (is that what you mean by "linker file"?)
I'll leave the above in, in case it's applicable.  But more likely is
that file handles under DOS are a *finite resource*.  What does your
FILES= statement in CONFIG.SYS say?
    Hope this helps.
