Subject: add legacy futimes and lutimes functions
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=477e72ac4a263c163ddfd25b6e2371de0dd97e10

add legacy futimes and lutimes functions

based on patch by sh4rm4. these functions are deprecated; futimens and
utimensat should be used instead in new programs.
