__GNU_SOURCE is defined by the gnu platform to specify the
availability of their extensions. Unfortunately they don't have a
finer grained tool to distinguish different types of extensions they
provide. (BTW the same holds for gcc, that you only can tune with
version numbers.)
If I, as a user, define __GNU_SOURCE I expect to have the gnu
extension, if I then use strerror_r I expect to have their interface,
since this is documented like this. At least as it is now, I don't
think I have any means to distinguish the two platforms and to know
which version of strerror_r I would receive.
