Greetings, Roland Mainz!

Very. Bad. Idea.

If your idea is to use same Cygwin install across multiple systems, then it is
a VERY bad idea. Due to the nature of fork call implementation in Cygwin, you
may experience unexpected behavior across different systems if DLL address
space layout come to be different from that where Cygwin was initially
installed.
