At first I would say here, that this feature is not so much
important to depend the other working gcc on it. Currently
I solve the problem (if I really need it) by simply defining
an other TMPDIR when running make, for instance

make TMPDIR=. ....

My first thought about using the cs selector is wrong like I tested
yesterday, since it will the same in different DOS boxes, but now I
found, that DJGPP provides also a function getpid() which reads out
(when I saw it correct) the BIOS area of the current time. So this
value could be used in the mktemp-template.

With the above hint, this is not needed.

In general I'm not a friend of such hacks, since it might cause
problems in the future (like you mentioned it already).
