In the above sentence "Cygwin" is meant to imply that you are actually
*using* Cygwin.  You are not, of course, using Cygwin if you specify
the -mno-cygwin option.

Normal Windows (i.e., what you're accessing when you specify
-mno-cygwin) does not provide a select() that can use pipe "file
descriptors", AFAIK.
