* tests/defs (ACLOCAL): Point to the installed aclocaldir is libtool is required. * tests/lex.test: Run AC_INIT once. * tests/ldflags.test, tests/listval.test, tests/suffix2.test: Libtool is required. * tests/header.test: Built a correct configure.in. * tests/defun2.test (configure.in): Be a bit respectful with Autoconf, close the macro invocations. * tests/confdeps.test: Even when not using aclocal, aclocal.m4 must be correct. * automake.in (scan_autoconf_traces): Add support for AC_CANONICAL_HOST, AC_CANONICAL_SYSTEM, A[CM]_PROG_LIBTOOL, AM_CONFIG_HEADER, AM_MAINTAINER_MODE. * tests/condincl.test (target): Better pattern, to avoid matching the definition of `target_alias' which is now properly discovered as an AC_SUBST by traces. * cond4.test: Better grep pattern: After all, why shouldn't TWO_FALSE be AC_SUBST properly. * tests/installsh.test (AUTOMAKE, ACLOCAL): Adjust.
