Subject: implement sincosf and sincosl functions; add prototypes
X-Git-Tag: v0.8.7~18
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5657cc58e5e135bba85c9a7045e10d8de4b1be0a;p=oweals%2Fmusl.git

implement sincosf and sincosl functions; add prototypes

presumably broken gcc may generate calls to these, and it's said that
ffmpeg makes use of sincosf.
