Brian is right.
GLAPI controls symbol visibility, both on unices (i.e.,
_attribute__((visibility("default")))) and windows (i.e.,
_declspec(dllexport).
GLAPIENTRY controls the calling convention (i.e., __stdcall presence or
absence).
This can be easily seen on top of GL/GL.h.
So in summary, GLAPI can and probably should be removed for _mesa_*
functions. GLAPIENTRY cannot.
