Subject: add missing multicast socket options to netinet/in.h
X-Git-Tag: v0.9.9~27
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=119645b6bb6578cc28718ab427e4b23860d67161;p=oweals%2Fmusl.git

add missing multicast socket options to netinet/in.h

based on linux headers add the missing MCAST_* options
under _GNU_SOURCE as they are not in the reserved namespace
(this api was originally specified by RFC 3678)
