"fork()" does not exist on Windows, nor does the concept of parent and child
processes.  Cygwin and similar Unix emulation band-aids jump through some
major hoops to recreate this.

Mingw32, is a purely native Win32 version of gcc, which uses the Microsoft
Windows supplied "msvcrt.dll" as the basis for it's C runtime, as does MS
Visual C. For these reasons, fork() is not part of Mingw32.
