I'm linking with GlU32.Lib and OpenGL32.Lib found in a "windows 
sdk" folder on my system with a windows search.  I converted them 
to OMF using the coffimplib tool provided by digital mars.  So 
this worked for the OpenGL32.Lib and got rid of those errors but 
the GlU32.Lib symbol errors persist.

Thank you!
