... you first have to correct a typing mistake in line 48 of glprocs.c:
#define wglGetProcAddress glXGetProcAddresARB
#define wglGetProcAddress glXGetProcAddressARB
(tested with the latest glext.h and glxext.h on SuSE Linux 8.2)
Thought anyone would like to know, if you mess with extensions some times.
I just wonder why they didn't include support for more recent stuff than OpenGL 1.2 and 1.3 ?
