fork() in Cygwin has to be pretty stable since it is fundamental to a
UNIX/Linux system.  Cygwin doesn't implement "clone()" however.  It is
theoretically possible to do so but it wouldn't be trivial.

This isn't a compiler issue.  You'd have to find something similar to
Cygwin which implemented clone().  Or add the functionality yourself.
