installing libGLU-devel solved that problem and I added it
to my notes for next time.  Thank you.

The program IS working but I had to do one additional thing
that I do not understand why.

I got a popup message saying that the program could
not run because it could not find cygXm-2.dll
In the bin folder of the Xp system computer (where
I had updated my spare hard drive with cygwin about a month
ago) I had two files:
cygwin/bin/cygXm-2.dll
cygwin/bin/cygXm-4.dll

but in the new install on the Windows 7 computer I had only
cygwin/bin/cygXm-4.dll

So I simply copied cygXm-2.dll from the other computer
to the new and my compiled and linked program runs OK.

  cygwin/bin/cygXm-2.dll  -> lesstif-0.95

  cygwin/bin/cygXm-4.dll  -> motif-2.3.4-1

You use the cygwin setup program to install the libGLU-devel package.

For the X11 GL/glu.h, you need to install libGLU-devel and its dependencies.

I downloaded cygwin with X, Open GL, and the g++ compiler four years ago
on a Windows XP system.  I have now replaced that computer
with an I7 computer running Windows 7.  I included all the packages
from my notes before, but I selected the 32 bit version of cygwin.
Compiling the exact same source code with what I was using before:
  g++ -c -O -m32 -Wno-deprecated
I now get the error about the header file glu.h:
/usr/lib/gcc/i686-pc-cygwin/4.7.3/../../../../include/w32api/GL/glu.h:68:79: 

error: expected `)' before `*' token

I searched the web and your archieve and can find no answer.

I will also mention that on the prior XP system, I had lost the hard dive
about a month ago.   Downloading cygwin etc. to my spare XP hard drive
resulted in all kinds of error messages about the header files when
I tried to compile the same code.
So I tried to simply copy over the cygwn directory a backup from the
crashed drive.  I then ran the cygwin setup to update (not sure why
I did that).  But I was then able to compile and link my program.
I would like to know what is going on rather than continue with trial
and error.  Thankyou to anyone who can respond.
