Subject: src/misc/mtime.c:
X-Git-Tag: 0.9.0-test0~11132
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=df0cb344c487f0ccd229ec21093a0fb852d49f12;hp=bd475b063164cc97addcc8088c6090306bc469a4;p=vlc

src/misc/mtime.c:
 - Don't use TIMER_ABSTIME which sucks (at least on Linux with HZ=1000)
 - Cosmetic
configure.ac:
 - Check for clock_nanosleep() rather than clock_gettime(), as it is more
   recent and we need both.
