This silences the warnings in inet_ntop and strptime; I'll let
Bruno deal with the warning in vasnprintf (I don't want to
touch that twisty maze of ifdefs).  There, it might be easier
to just unconditionally declare:

int has_width _GL_UNUSED;

than to figure out the right set of #ifdef guards on when to
declare vs. when to use.

  inet_ntop: silence gcc warning
  strptime: silence gcc warnings
