3 * C's strtoul skips whitespace, accepts "-1" for an unsigned (wrapping it), "0x10" with base 0 and
4 * stops at the first bad byte; Rust accepts none of that. The fleet's text formats are parsed by
5 * these so a C member accepts and refuses exactly what a Rust member does. All return false on
6 * anything Rust's parse would refuse (empty, junk, overflow), leaving *out unchanged. */
