* lib/m4sugar/m4sugar.m4 (m4_copy): Add second implementation for public use. (_m4_copy): New macro, which preserves pushdef stacks. (_m4_defun_pro_outer): Bypass it, for speed. (m4_init): Bypass new implementation, since it breaks on m4_defn. * bin/autoupdate.in (handle_autoconf_macros): Likewise. * lib/autoconf/general.m4 (AC_PREREQ): Undefine before redefining, now that m4_copy checks this. * doc/autoconf.texi (Redefined M4 Macros) <m4_copy>: Document this, as well as m4_rename. * lib/autoconf/autoconf.m4 (m4_copy): Temporarily redefine when renaming builtins. * NEWS: Likewise. * tests/m4sugar.at (m4@&t@_defn): Enhance test.
