  Yeah.  But I'm (finally) OK with using C99 features.  I avoided them
for a while, because so many systems didn't support even C89.

  So changing all of the code to use %zu for size_t, and %zd for ssize_t
is probably OK.

  I would STRONGLY avoid casts.  They're an ugly brute-force solution to
a simple problem.
