Alternatively, consider *NOT* to ship the Cygwin DLL with your
application, and if you do, please test if a normal Cygwin release is
already installed on the machine and use it if it exists instead of
installing your own Cygwin DLL.  Otherwise your users will have trouble
no end.  Also, keep in mind that this mailing list will not support your
users which have trouble with multiple Cygwin DLL installations.  It's
not supported.  If possible, don't do it.
