	Using the latest tools allows gzip to build correctly on hosts
	conforming to POSIX 1003.1-2001.
	
	* configure.in (match): Use AC_LIBOBJ; Autoconf 2.53 requires it.
	(LIBOBJS): No longer need to subst, since AC_LIBOBJ does it.
	(AC_PREREQ): Bump to 2.53.

	* Makefile.am (install-exec-hook, remove-installed-links):
	Work even when configured with --program-transform-name.

	* gzip.c (license_msg): Update copyright.
	(z_len): Now of type size_t.
