BZ #16632: Change [_BSD/_SVID]_SOURCE warning.
Source packages that need to support both 2.19 and 2.20 will need to decide to use _BSD_SOURCE and _SVID_SOURCE vs. _DEFAULT_SOURCE. The difficulty in making that decision is that __GLIBC_MINOR__ is itself defined in features.h, but you want to set the feature test macros before including features.h. Therefore to ease the transition we should disable the warning if _DEFAULT_SOURCE is also defined. https://sourceware.org/ml/libc-alpha/2014-02/msg00666.html https://sourceware.org/glibc/wiki/Release/2.20#Packaging_Changes
