In my MinGW directory (MinGW 5.1.3), glext.h is at version 11 (2002/03/22)
and blDeleteObjectARB is not defined.

Downloading latest glext.h from www.opengl.org shows latest version is 40
(20080324), and there is a definition for blDeleteObjectARB...

So this was introduced somewhere between V11 and V40; from there I see only
2 solutions:

1) get latest MinGW and check if blDeleteObjectARB is defined in glext.h
2) downlad openGL headers from www.opengl.org and put the new ones in MinGW

Now another question: what happens if graphic card driver does not support
the openGL extensions used here?
