Subject: [PATCH 1/1] sched: workaround glibc _POSIX_PRIORITY_SCHEDULING bug.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Close #223.
* configure.ac (AC_CHECK_HEADERS): Add sched.h.
* ext/posix/sched.c: Remove unistd.h; Predicate use of priority
scheduling APIs on presence of sched.h instead of
_POSIX_PRIORITY_SCHEDULING macro erroneously defined by glibc on
Linux.
