The variable is not buffer-local and it doesn't seem to be let-bound
while compilation-process-setup-function is run, so I suspect that
this code might end up modifying the global value of process-environment.

Since this is copied more or less verbatim from eshell/em-unix.el,
maybe John can explain why it is safe to do thing this way ?
