_BSD_SOURCE (deprecated since glibc 2.20)
Since glibc 2.20, this macro is deprecated. It now has the
same effect as defining _DEFAULT_SOURCE, but generates a com‐
pile-time warning (unless _DEFAULT_SOURCE is also defined).
Use _DEFAULT_SOURCE instead. To allow code that requires
_BSD_SOURCE in glibc 2.19 and earlier and _DEFAULT_SOURCE in
glibc 2.20 and later to compile without warnings, define both
_BSD_SOURCE and _DEFAULT_SOURCE.
