33 work around that problem by just adding the declaration there, or by
34 eliding the inline functions in the absence of __USE_GNU. But either of
35 these would result in unoptimized calls (because no inline version of
36 __stpncpy will have been defined), and there may be other niggling
37 problems lurking. Instead we simply insist on _GNU_SOURCE for
