/* in SDKs > 10.6 this Apple header does not include glext.h.
|
|
* Including it causes redefinition errors that are hard to
|
|
* overcome in ports, eg mesa, so we block the loading of
|
|
* glext.h here on older systems for consistent behaviour with newer systems

|
|
* multiple times and should have the same effect each time
