Btw, I wrote it >= instead of > to silence some idiotic static analysis.
On a 64bit system U64_MAX can't be greater than SIZE_MAX so Gcc will
complain.

However this test only affect 32bit systems and > and >= SIZE_MAX on a
32bit system are effecitively the same.  Neither one is ever going to
happen.
