While the patches fixed `mktemp()' they did not solve the
problem directly (but "only" pointed me to the right direction:-):

When `gpc.exe' (or `gcc.exe' for that matter) chooses a new
temporary file, it chooses one base name (say, "ccaaaaaa") and
appends several suffixes to it ("ccaaaaaa.i", "ccaaaaaa.s", etc.).

Now a second instance of `gpc.exe' starts work and tries to
choose a new temporary base name.  Since no file "ccaaaaaa"
(without suffix) exists, `mktemp()' has no problems returning
the same pattern again.

I could solve the problem by telling `gpc.exe' to create a
dummy file "ccaaaaaa" seen by `mktemp()'.

Another possible solution would be to tell `mktemp()' to look
out also for "ccaaaaaa.*" and not only for "ccaaaaaa".

Again:  Thanks a lot for your big help!  :)
