Problem trying to build Cygwin X server from source

[Mark Lillibridge <mdl@alum.mit.edu>]

    This is xserver-cygwin-1.14.3-1, the latest as of several weeks ago.

    The part that is failing (make done in
/usr/src/xorg-server-1.14.3-1/src/xserver-cygwin-1.14.3-1/hw/xwin/glx):

echo :/usr/share/opengl/api

    Any suggestions?  The online documentation is seriously out of date,
predating the use of cygport.

- Thanks,
