rather than using the installed includes, for target builds.
If cygwin, override function list only for target builds.

Note from DJ: I waited a week for gcc approval and got none, but
we need this patch for cygwin builds *now*. I'll fix it later if
need be.

The string pointer is advanced to far before the check to set
