libtool/libtool.m4
Gary V. Vaughan 2b5fa736e6 libtool.m4 (AC_PROG_LIBTOOL): Removed, as it was triggering a 
bug in Autoconf-2.13 AC_REQUIRE implementation which inserted
some of the expanded tests too early in the generaated configure.
(_AC_PROG_LIBTOOL): renamed to AC_PROG_LIBTOOL, and defines
itself to an empty expansion to prevent multiple expansions.
configure.in (AC_LIBTOOL_SETUP): Replaced by a call to
AC_PROG_LIBTOOL now that the AC_REQUIRE bug has been worked
around.
