[FFmpeg-devel] [PATCH] all: add _DEFAULT_SOURCE locally wherever needed

[Ganesh Ajjanagadde]

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.
