MSYS does not depend on cygwin, BTW. It's entirely standalone. They
both have to implement fork() using Windows calls though, which can
never be efficient.

to forking the compiler, preprocessor, assembler, collect2 etc.
configure is even slower (it takes over half an hour to run the
gimp-print configure script, c.f. 20 secs on Linux) since it forks
over 5000 processes.
