I love code like this:

extern int errno; /* some systems don't have this in errno.h */

after the following in a central header:

#ifndef _WIN32
#include <sys/errno.h>
#else
#include <errno.h>
#endif

Sure, e.g. NetBSD doesn't define errno in sys/errno.h, but why should it?
So, let's just fix this.
