I seem to remember that Cygwin emulates an awful lot of Unix/Posix
functionality in its DLL.  Others will be more qualified to comment on
this, but the mere use of WINDOWSNT might not necessarily mean that
SIGCHLD can't work: it might be provided by the emulation layer.

Could somebody who actually knows Cygwin by more than heresay fill in
the details and tell whether I am completely wrong here?
