later w32api package required to build cygwin

[David Starks-Browning <starksb at ebi dot ac dot uk>]

Greetings,

I've been attempting to build cygwin1.dll from within Cygwin.

I checked out winsup from cvs, and am building in a separate
directory.

It fails because my installed /usr/include/w32api/winioctl.h (from the
w32api-2.0-1 package) is out of date compared to that in cvs
(winsup/w32api/include/winioctl.h).

Is there a "good" way to deal with this?  It's easy enough for me to
fix this one file, but I only spotted it because make failed
completely.  It's likely that there are other differences between my
Cygwin installation and the winsup CVS, that might cause me to build
cygwin1.dll incorrectly.

Is there some way that

  #include <winioctl.h>

(for example) can automatically look in .../winsup/w32api/include
instead of the standard location /usr/include/w32api?

Thanks very much.

Regards,
David
