Not sure if drivers will want this definition, so I'd wouldn't put exported
for them now.

And maybe two definitions inside window.c and exa_glyphs.c scopes sounds
better to avoid unnecessarily global references. Something like:

#ifdef HAVE_ARC4RANDOM
#define OSRAND(x) arc4random(x)
#else
#define OSRAND(x) rand(x)
#endif


Well, I guess one would suggest this trick inside autoconf foo...
