glut.h in mingw

Hi,

This thread is derived from Re: Predefine _M_IX86 in gcc.

I was mentioning earlier the oddity of having the glut libraries but
not the header. Instead of removing the libraries, it would really nice
to add the header to the mingw package!

I was curious why I needed to do a certain hack on the latest glut.h
(specifically, to remove some prototypes that the linker expects and
dies when it doesn't find them in libglut32.a).
Eventually, I realized that libglut.a and libglut32.a currently supplied
with mingw belong to an older version, i.e. 3.6 (latest stable) instead
of 3.7.6 (late beta).

So I suggest to include glut.h from

  http://www.opengl.org/developers/documentation/glut/
  http://www.opengl.org/developers/documentation/glut/glutdlls36.zip

into

  /mingw/include/GL/


The nicest part is that it works unmodified with mingw, and even with
cygwin if -DWIN32 is passed to the cygwin-gcc cmd line.

As a side note (related to the other _M_IX86 thread), this is a version
that does include <windows.h>, unlike the newer ones. At least it's good
that it *works*.


My tests show that the executables run well with GLUT32.DLL from 3.6
to 3.7.6. To test it yourself, you should find plenty of test programs.
But if you are in a hurry, you can get a very basic one from here:
