    _______________________________________________________

Details:

In current GCC, build will fail with the following output:

  CC       walker.o
walker.c: In function 'lang_wanted':
walker.c:481:1: error: function might be candidate for attribute 'pure' if it
is known to return normally [-Werror=suggest-attribute=pure]
 lang_wanted (char const *lang_name)
 ^~~~~~~~~~~
cc1: all warnings being treated as errors
make[2]: *** [Makefile:1500: walker.o] Error 1


A solution is to add _GL_ATTRIBUTE_PURE to lang_wanted().

See attached patch.
