Hello,
The changes to <GL/glu.h> in w32api-2.5 expose a problem with the glut.h in opengl-1.1.0-7 package, file <GL/glut.h>. The problem is that whcar_t is now required to be defined by /usr/include/w32api/GL/glu.h, however glut.h does not do so.
I think you meant glu.h in the above line.
I'm not sure where the _best_ place to put a definition is; for myself I have put it at line 153 of glut.h. Others may wish to do so too, and perhaps a patch to the opengl package is in order if other more knowledgeable folks concur.
No glut function uses wchar_t in any form, so IMO it does _not_ belong there. The only thing GL-related that uses wchar_t is gluErrorUnicodeStringEXT, an M$-specific extension to GLU; from w32api-2.5 usr/include/w32api/GL/glu.h :
GLAPI const wchar_t * APIENTRY gluErrorUnicodeStringEXT (GLenum error);
From w32api-2.5 announcement:
2003-09-24 Dimitri Papadopoulos <[EMAIL PROTECTED]>
* include/GL/glu.h (gluErrorUnicodeStringWIN): Add macro function. MSDN suggests using gluErrorUnicodeStringWIN instead of gluErrorString, as it allows both ANSI and Unicode error strings.
* include/GL/glu.h (gluErrorUnicodeStringEXT): Make the returned pointer const for consistency reasons.
2003-09-24 Dimitri Papadopoulos <[EMAIL PROTECTED]>
* include/GL/glu.h (gluErrorUnicodeStringEXT): Add function. Function exists in glu32.def but is undocumented on MSDN. A Google search came up with this declaration.

* include/GL/glu.h: Rewritten from scratch. Started from GLU 1.3 headers from OpenGL Sample Implementation. Windows ships with GLU 1.2 so some constants and functions were removed. Then some typedef's and function declarations were reworked to look like the previous GL/glu.h.
So IMO, your patch below should be applied to glu.h by the w32api maintainers.
153,156d152
< # ifndef _WCHAR_T_DEFINED
< typedef unsigned short wchar_t;
< # define _WCHAR_T_DEFINED
< # endif
The only other workaround I can see is adding an #include <windows.h> before every #include <GL/glut.h> which is neither elegant nor in the spirit of GLUT's philosophy of hiding platform dependencies.

I modified the above line (was a plain email adresss). Beware that Spam bots search lists like this one for new targets for their junk.
I CC'd the MingW list about this issue.
