<pre>gl.h and osmesa.h define PRAGMA_EXPORT_SUPPORTED and then use "pragma export
on", "pragma export off" if that is defined.
#if (defined(__BEOS__) && defined(__POWERPC__)) || defined(__QUICKDRAW__)
# define PRAGMA_EXPORT_SUPPORTED 1
#endif
On my mac, this ends up being true somehow (I suppose something ends up
defining __QUICKDRAW__), and then clang warns
../../third_party/mesa/src/include/GL/gl.h:124:9: warning: unknown pragma
ignored [-Wunknown-pragmas]
#pragma export on
^
It looks like this is only used for old platforms, so I'd suggest just removing
the whole "pragma export" stuff.</pre>
