Well, to start with the author has an error in his header 
file GLUT.H

------------
/* define APIENTRY and CALLBACK to null string if 
we aren't on Win32 */
#if !defined(WIN32)
#define APIENTRY
#define CALLBACK
#endif
------------

The macro defined under Win32 is __WIN32__ and not WIN32. 
The effect of the failed test for the existence of the 
macro is to change the declared calling convention for 
the functions and therefore the public names that will be 
given to those functions.  This results in function not 
found errors. 

I tried to build the file program1.cpp from the 'sbenavides'
link which you provided.  After altering the macro name it 
turns out that this GUI program must be built in Console mode, a fact that the web site should have mentioned.  After 
changing to the console mode option -WC the program built
but when run it failed because the provided GLUT32.DLL 
requires two other DLL's that are not provided, OPENGL32.DLL 
and GLU32.DLL

A web search turned up these links for them:

  http://www.shorl.com/fujepritrepruse
  http://www.shorl.com/hopobradigrure

After downloading and virus scanning them I was met with an 
error box complaining that the OPENGL32.DLL file requires 
a later version of Windows than I am running. 

In other words, your complaints are related to the site 
from which you got that code and not with the compiler.
