Could this issue be related to the general problem that lots of GO32
error msgs goto to stdou instead of stderr?  I reported this some time ago.

E.g., if you do:

	go32 a.out myprog myargs > outfile

and go32 cannot open its paging file (e.g., you are running on a network
and do not have write rights to the root), what you get is a 47 byte outfile.
