+Subject: [PATCH] Fix build with non-wchar toolchains
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit a7f5650e6549e1b5c4e2e1fa30eee19de6bcbe7a added two functions to
+mbutil.c but forgot to add defines for HANDLE_MULTIBYTE causing build
+errors with toolchains without wchar support:
+
+../mbutil.c: In function ‘_rl_mb_strcaseeqn’:
+../mbutil.c:594:3: error: unknown type name ‘mbstate_t’
