[ogl-sample] Compiling libGLU on Irix-6.5 with gcc-2.95

[Wolfram Gloger <Wolfram.Gloger@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hello,

Recently, I got stuck developing an OpenGL application on Irix 6.5
with gcc, because /usr/lib32/libGLU.so brings in libC.so, which
clashes with libstdc++.so (as supplied by gcc).  The results where
crashes even before main was reached (the global cin and cout objects
are messed up).

Now, thanks to the sample impl. release, I seem to have succeeded in
building _with gcc-2.95_ my own libGLU.so depending only on libstdc++
(not libC), and my app runs fine ! :-) (So far just limited testing,
though.)

One trivial patch is appended below; with this the compile of libGLU
runs through even with `c++ -ansi' as the C++ compiler.

Would I be allowed to distribute the resulting libGL.so binary as a
service to other gcc users on Irix 6.5?

Regards,
Wolfram.
