Please give exact configuration paramters.  That is, are you using
`make linux-osmesa'?  Or the autoconf build system?  If the latter,
either attach your config.log (best) or give the ./configure line you
used.

Fix for glBlendEquationSeparate

glBlendEquationSeparate/glBlendEquationSeparateEXT was marked as not a static_dispatch function. This one liner will make glBlendEquationSeparate exported symbol.

Mesa exports this symbol now. No idea when that changed. Closing.

So... there actually was no bug before.  glBlendEquationSeparate isn't part of the ABI, so it's not supposed to be exported!  Applications are required to use glXGetProcAddress to access these functions.
