[Xastir-Dev] Makefile optimizations for low memory machines

[David Flood]

This was under Windows 98 so the swap size is set to Auto (base memory of
the laptop is 40M so well under even what Cygwin wants).  LD did finally
finish...approx 16 hours after starting.

Then I got the 0 height/width error from the resulting .exe so I set Cygwin
to the side and I'm now trying to get XF86_SVGA to talk to the C&T card
under SUSE 8.2.

Just tried a "low-memory" machine with Cygwin.  In this case, low
memory means 128MB running Win2k.  Win2k likes to use 109MB or so
doing nothing (with virus scanning running).

I had to become admin, increase the max size of the swap area for
each drive, log back in as a normal user, then Windows popped up a
message saying it was low on virtual memory and increasing it for
me.

Before I did that, the link stage just seemed to repeat over and
over, as evidenced by "ld" in Task Manager going from around 10MB to
about 100MB, then repeating.  It would never finish.

Try cranking up your virtual memory settings to see if "ld" can
complete the final link stage.
