 I just stumbled accross https://lwn.net/Articles/634207/ which states:

 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).

 We use this in some of our option lists to make {{{M_PI}}} and
 {{{strdup}}} visible.
