Since I tend to use windows a bit I will go ahead and review the
overall patch ( including libepoxy ).

1) Requiring unix-specific features to compile on windows will drive
away developers. ( I am talking about the pkgconfig requirement ).
It's not exactly a good idea to require this on windows.
2) libepoxy itself uses autogen and autoconf... This is an absolute
nightmare for windows developers. I would like to suggest adding cmake
build options to libepoxy ( Mainly to help improve the build process
on systems that lack libepoxy and also make it easier to integrate
within piglit itself )
3) What versions of python are expected for libepoxy to generate the
dispatch tables? Based on what I am seeing it will accept any python
version ( so long as it uses the python as the interpreter executable
).
4) The requirements on Mac OSX are a bit much, This probably should be
changed to make use of
