When a program is compiled with -pg, it causes invocation of _monstartup
and it calls atexit, the problem is, _mcleanup is called twice in forkee!
That's because of _GLOBAL_REENT is copied when a process is forked.
Then we have two _mcleanup. (_monstartup is with __constructor__
attribute.) and this is not we wanted.
the same thing can be applied to any atexit call in cygwin which doesn't
cares about forkee.

Why are you talking about this here when Corinna asked you questions in
cygwin-developers?
