X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=030e52639248ac8417a4934298caa78c21a228d1;hp=030e52639248ac8417a4934298caa78c21a228d1

add getopt reset support

based on proposed patches by Daniel Cegiełka, with minor changes:
- use a weak symbol for optreset so it doesn't clash with namespace
- also reset optpos (position in multi-option arg like -lR)
- also make getopt_long support reset
