[Mesa-dev] multiple versions in version string

I am trying to get some regression tests to run in Xvfb.  On my
workstation, the GL_VERSION string from this is:

  1.4 (2.1 Mesa 7.7.1)

according to glxinfo.  The extensions fairly clearly show 2.x features.
Is it perhaps the case that 2.1 features were available in 7.7.1, but
not /all/ 2.1 features, and thus this was labelled incorrectly?  The
version string seems "fixed" in more modern versions.

In any case, the above version string breaks projects like GLEW
-- one application I have breaks because GLEW doesn't try to load
glGenBuffers, thinking it will not be there.  A string like the above
suggests that GLEW should just try to load whatever it can, and just
ignore the version string from the library.

Thoughts?
