   * For providing a substitute for a function that is missing on some

       # if !@HAVE_FOO@

       _GL_CXXALIASWARN (foo);
       #elif defined GNULIB_POSIXCHECK
       ...
       #endif

   * For providing a replacement for a function that exists on all platforms,
     but is broken/insufficient and needs to be replaced on some platforms:

       #if @GNULIB_FOO@
       # if @REPLACE_FOO@
       #  if !(defined __cplusplus && defined GNULIB_NAMESPACE)
       #   undef foo

       _GL_CXXALIASWARN (foo);

       #endif

   * For providing a replacement for a function that exists on some platforms
     but is broken/insufficient and needs to be replaced on some of them and
     is additionally either missing or undeclared on some other platforms:
