Hi Brian,

The only build difference I can think of is where the OpenGL header is
included from.  Can you do a diff between the various gl.h versions?

Robert,

I'm not disputing it is a Cygwin issue especially after doing a package
search
I see that cygwin has an OpenGL which is in /usr/include/GL and then the
X11
version in /usr/X11R6/include and then the Win32api version in
/usr/include/w32api.  The first usr/include/GL has not been updated since
April-May 2001 and the X11 date to Apr 20 2005 but the W32API version was
updated Mar 26 of 2007 so there could be something there.  I checked
however
and the 3 files in the /usr/include/w32api/GL all have the same sizes as
the
previous version which date back to Nov 2006.  I will try updating a
previous
version and see if it starts compiling again.

on the other side of the coin any chance this could be an makefile issue
since
in a discussion on March 29th in this thread:

http://openscenegraph.net/pipermail/osg-users/2007-March/075657.html

I was questioning Alberto in this thread after he said he successfully
built
OSG in Cygwin and I was getting the Tesselator error then.  He replied he
had
been building the old makefiles which following the thread I then tried
and
successfully built using the old makefiles as well.   Then on April 13 in
my
post:

http://openscenegraph.net/pipermail/osg-users/2007-April/076139.html

I reported some success at building Cygwin using the new cmake and things
seemed to be working unless I really screwed up that build.

Now however it appears the error in Tessellator has returned.
