Comment (by pulkomandy):
The way it work in glibc is that the user defines _GNU_SOURCE, and
features.h defines {{{__USE_GNU}}} and other {{{__USE_*}}} stuff.
Our public features.h works differently, as I don't think the internal
{{{__USE_*}}} defines are very useful and they are confusing to track. So
when taking headers from glibc and making them public, we have to be
careful about this.
I would leave these as is for now unless there are problems compiling
things because of this? The BSD extensions that we have in libbsd are
quite useful, but the things glibc adds or goes against POSIX for, I'm not
so sure.
