Sorry, I wrote this based on the Microsoft documentation, I didn't
realize mingw doesn't support those the Microsoft stdlib.h. My
googling on mingw and random doesn't seem to turn anything up.
rand() isn't supposed to be used in multi-threaded programs. How
badly it fails depends on a particular implementation, but I can't
find any documentation the MINGW rand() implementation.

If we need to, we can go back to the posix_rand_r() in my previous
commit but it isn't exactly fast since it uses a mutex. Maybe some
windows developer can speak up on how to get decent pseudo-random
numbers in a thread-safe way using mingw?

As for srandom() we can just put a stub in compat.h for that on
windows, it just initializes the pseudo-random number generator.
