    /* The three most frequent use cases of these macros are:
    
       * For providing a substitute for a function that is missing on some
         platforms, but is declared and works fine on the platforms on which
         it exists:
    
           #if @GNULIB_FOO@
           # if !@HAVE_FOO@
           _GL_FUNCDECL_SYS (foo, ...);
           # endif
           _GL_CXXALIAS_SYS (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

           #elif defined GNULIB_POSIXCHECK
           ...
           #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:
