 > As per GLIBC 2.20 release notes[1]:

 >     The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
 >     supported; they now act the same as _DEFAULT_SOURCE (but generate a
 >     warning). Except for cases where _BSD_SOURCE enabled BSD interfaces
 >     that conflicted with POSIX (support for which was removed in 2.19),
 >     the interfaces those macros enabled remain available when compiling
 >     with _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without
 >     any feature test macros defined.
