* | avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis2016-01-27
| | | | | | | | | | | | | | | | | | | | Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* | all: add _DEFAULT_SOURCE locally wherever neededGanesh Ajjanagadde2015-10-04
| | | | | | | | | | | | | | | | | | Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE. The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros. This solution is on the lines of the one in commit af1818276ef271af98e2e2bbabb4dc875b4fa7d8.
