+       Partial m4sugar merge from autoconf: builtins, version.m4.
+       * data/m4sugar/m4sugar.m4 (changeword): Nuke.
+       (m4_prepend): Remove, as it is unused and inherently quadratic,
+       whereas m4_append is linear in newer m4.
+       (m4_mkstemp): New builtin.
+       (m4_symbols): Make rename conditional.
+       (m4_version_prereq): Ensure fatal error if used in bison, which
+       intentionally lacks version.m4.
