* m4/amversion.in (_AM_AUTOCONF_VERSION): New macro. (AM_SET_CURRENT_AUTOMAKE_VERSION): Call it. * aclocal.in (trace_used_macros): Trace _AM_AUTOCONF_VERSION. (write_aclocal): Output a check for Autoconf's version in aclocal.m4. Doing so ensures that users cannot build configure and Makefiles with two different autoconf versions. Report from Noah Misch. * tests/missing4.test: New file. * tests/Makefile.am (TESTS): Add it.
