TMPDIR should have forward slashes by virtue of DJGPP.ENV, unless
TMPDIR is already set outside the DJGPP program you run (gawk and
Bash in these cases).

Bash _must_ have TMPDIR forward-slashed, or else lots of scripts will
fall apart.  I don't know about Perl, but I think you are right
assuming it should get the same treatment.

As for TEMP, I don't think Unix programs use it, so it could be left
at its backslashed form.
