Subject: add public declaration for optreset under appropriate feature profiles
X-Git-Tag: v1.1.24~31
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a882841baf42e6a8b74cc33a239b84a9a79493db;p=oweals%2Fmusl.git

add public declaration for optreset under appropriate feature profiles

commit 030e52639248ac8417a4934298caa78c21a228d1 added optreset, a BSD
extension to getopt duplicating the functionality (also an extension)
of setting optind to 0, but failed to provide a public declaration for
it. according to the BSD documentation and headers, the application is
not supposed to need to provide its own declaration.
