d3d8 compile issues

[Ann and Jason Edmeades]

Hi Eric,

Can you send me (and copy Raphael) your gl include directory.

FYI The whole point of the changes Raphael made is to avoid this issue
of 
many #ifdefs in the code to handle gl13, gl14, _arb and _ext names. It
should also allow runtime determination of support rather than compile
time determination (ie packages become possible), and finally should
prevent
this problem (once we have it right).

I'm agreeing with Raphael now - It would be so easier to define our own
gl
headers :-)
