just a nit pick:
INT32_MAX is not mentioned in the POSIX page, just drop it.

Betreff: [patch] random.3: wfix: RAND_MAX is for rand(3)
POSIX fixes random()'s range at 2^31-1; RAND_MAX may be smaller on some
platforms (even though with glibc or musl on Linux they are the same).

Thanks for confirming, Walter. I forgot to mention I was happy to
provide a patch -- suggested fix in this git-format-patch message.
