I suspect this is not Windows related.

Yes, we rely on Fmake_temp_file_internal in Fcomp__compile_ctxt_to_file
to decide the output filename to be passed to libgccjit when asking for
compilation.
There should be no conflict unless more then one process is trying to
compile the same file (not sure ATM if this is what we are seeing here
and why this should be happening).
