Subject: set optopt in getopt_long
X-Git-Tag: v1.1.6~14
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0217ed72f986d78b177f1a014e93f2150105bb44;p=oweals%2Fmusl.git

set optopt in getopt_long

this is undocumented but possibly expected behavior of GNU
getopt_long, and useful when error message printing has been
suppressed.
