There is mistype (or bug) in "QtCore\qconfig.h".
This causes problem when trying to use no-ES OpenGL headers and "glew" library.

Problem lines:

#if defined(QT_OPENGL_ES) && defined(QT_NO_OPENGL_ES)
#undef QT_OPENGL_ES
#elif !defined(QT_OPENGL_ES)
#define QT_OPENGL_ES
#endif

#if defined(QT_OPENGL_ES_2) && defined(QT_NO_OPENGL_ES_2)
#undef QT_OPENGL_ES_2
#elif !defined(QT_OPENGL_ES_2)
#define QT_OPENGL_ES_2
#endif

Note, that even if you define "QT_NO_OPENGL_ES_2", "QT_OPENGL_ES_2" will be defined anyway.
This is definitely bug, as there many valid defines in this file, except those ones.

FIX attached.

Update:
I've used Qt 5.0.0 binary distributive for Windows VS2010.

By default QT_OPENGL_ES is undefined. So QT_NO_OPENGL_ES make no effect.

Maybe QT_OPENGL_ES should be predefined (because this Qt built with GLES, not "desktop"), then QT_NO_OPENGL_ES would make sense.
