Not sure what is going on. One potential problem could be that you
don't have any of the following environment variables defined: TMPDIR,
TMP, TEMP. If none of these are defined, Emacs will try to open the
temporary file in C:/temp, and if you don't have that, either, it will
fail. It will also fail if one of the above environment variables is
set, but points to a non-existent directory.
djgpp.env, the file all DJGPP programs read to set up their
environment, defines TMPDIR to point to the 'tmp' subdirectory of the
directory where you have djgpp.env. Could it be that this directory
doesn't exist on those machines where you see the problem?
If none of the above helps, I'm clueless. If you can build Emacs
yourself and you can debug the resulting binary with GDB, perhaps you
could step through the code (I can tell you where exactly) and report
what you see. I myself don't have access to a plain DOS machine for a
long time now, and can only run the DJGPP build of Emacs on Windows.
