* aclocal.m4 (AC_PROG_CC_LOCAL): Renamed to hurd_PROG_CC.
(AC_PROG_CC_WORKS_LOCAL): Renamed to hurd_PROG_CC_WORKS.
* configure.in: Use hurd_PROG_CC instead of AC_PROG_CC_LOCAL.
(AC_PREREQ): Require 2.12.
(AC_CANONICAL_HOST): Give helpful error messages for likely cases of
bogus host specs.
(crypt check): Don't do AC_CHECK_FUNCS to get HAVE_CRYPT,
just check for -lcrypt to set $LIBCRYPT.
