Possible tweak for tm2unixtime.c

Hello. I'm not sure, but I believe the following do {} while code is pointless in /ext/date/lib/tm2unixtime.c (located here: https://github.com/php/php-src/blob/af6c11c5f060870d052a2b765dc634d9e47d0f18/ext/date/lib/tm2unixtime.c) The code in question (appears a lot): do {} while (do_range_limit(0, 60, 60, &rt->s, &rt->i)); The method do_range_limit() will always return 0, so why not just call it like so: do_range_limit(0, 60, 60, &rt->s, &rt->i); And remove the do {} while loop. There may be a reason why that loop code is there, but I'm not seeing why. More than happy to be wrong. -Tig
