[Robert Osfield]

Hi Terry,

I have just tried out GLES1 and GLES2 profiles and got the same
compile error on my Kubuntu 15.04 system.  I have added some #ifdef
guards around the problem code and things now compile cleanly.

I also came across a build error when compiling osgQt due
GLuint64/GLint64 typedef so I've made a tweak to the GL.in so that it
now uses int64_t and uint64_t and this resolves the compile error.

These fixes are now checked into svn/trunk and OSG-3.4 branch.

Robert.
