I think that detecting Cygwin is _not_ so important. After all, using a
specific setup target, as in "make setup cygwin", should be enough when
run from the Windows command shell.

What could be fun however is to auto-detect Cygwin from the Bash
shell on Win32 though.. and this is certainly easy to do..

Again, I don't see why we should try to automatically detect Cygwin
on Win32 systems. It seems that this greatly simplifies the problem.

As to UWIN, NutCracker, etc.., I don't know enough about them to tell
