ar-lib: new 'AM_PROG_AR' macro, triggering the 'ar-lib' script * m4/ar-lib.m4: New macro AM_PROG_AR, which locates an archiver and triggers the auxiliary 'ar-lib' script if needed. * m4/Makefile.am (dist_m4data_DATA): Update. * automake.in ($seen_ar): New variable. (scan_autoconf_traces): Set it. (handle_libraries, handle_ltlibraries): Require AM_PROG_AR for portability. * doc/automake.texi (Public Macros): Mention the new 'AM_PROG_AR' macro. (Subpackages): Add AM_PROG_AR to the example. (A Library): Adjust recommendations for AR given the new AM_PROG_AR macro. * All relevant tests: Adjust to new portability requirements due to the new AM_PROG_AR macro. * tests/ar-lib2.test: New test, checking that AM_PROG_AR triggers install of ar-lib. * tests/ar-lib3.test: New test, checking that lib_LIBRARIES requires AM_PROG_AR. * tests/ar-lib4.test: New test, checking that lib_LTLIBRARIES requires AM_PROG_AR. * tests/ar-lib5a.test: New test, checking that AM_PROG_AR triggers use of ar-lib when the archiver is Microsoft lib. * tests/ar-lib5b.test: New test, checking that AM_PROG_AR triggers use of ar-lib when the archiver is a faked lib. * tests/ar-lib6a.test: New test, checking the ordering of AM_PROG_AR and LT_INIT. * tests/ar-lib6b.test: New test, checking the ordering of AM_PROG_AR and AC_PROG_LIBTOOL. * tests/ar-lib7.test: New test, checking that automake warns if ar-lib is missing. * tests/ar3.test: New test, checking that AR and ARFLAGS may be overridden by the user even if AM_PROG_AR is used. * tests/ar4.test: New test, checking that AM_PROG_AR bails out if it cannot determine the archiver interface. * tests/ar5.test: New test, checking that AM_PROG_AR runs its optional argument if it cannot determine the archiver interface. * tests/defs.in: New required entry 'lib'. * tests/Makefile.am (TESTS): Update. * NEWS: Update.
