+       glob: Avoid #define replacements in C++ mode.
+       * lib/glob.in.h: Include c++defs.h, warn-on-use.h.
+       (_gl_glob_errfunc_fn): New type.
+       (glob, globfree, glob_pattern_p): In C++, define a namespaced alias
+       symbol.
+       * modules/glob (Depends-on): Add c++defs, warn-on-use.
+       (Makefile.am): Update glob.h rule.
