Also in 2.20, the _BSD_SOURCE and _SVID_SOURCE feature test macros have been removed. The declarations formerly available under those macros are now under _DEFAULT_SOURCE, but, since it's the default, one need not set it explicitly. Roland's suggestion, though, was that most code would (continue to) want to use _GNU_SOURCE or one of the POSIX-specific macros. (See this article for an introduction to glibc feature test macros).
