OpenGL Prob w/ VC++ 6

Here is my problem - every time I try to build/link one of my OpenGL programs or an OpenGL example, I get the following three errors from my VC++ 6 comiler -

c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1135) : error C2144: syntax error : missing ';' before type 'void'

c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1135) : error C2501: 'WINGDIAPI' : missing storage-class or type specifiers

c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1135) : fatal error C1004: unexpected end of file found

Now the thing that really makes my angry, is that these are errors are in the MS supplied OpenGL header files! I don't understand it... If anyone out there can help me, I would be really really really gratefull (been trying to find the prob for two weekends now). Thanks for reading this, and thanks for any help you can offer. Rob.

WINGDIAPI is defined in wingdi.h. Typically, one must include windows.h
before the GL headers and windows.h will then include a whole pile of
other headers. Pre-compiling this stuff will really speed things up.
I always put the GL headers in stdafx.h these days because of this
(or stdhdr.h when I don't use MFC which isn't often.) Including the
standard afxwin.h before the GL headers will accomplish the same thing.

One possibility is that your #define conflicts with the library stuff. Place your #include belows the library #include and see what happens.
