Makefile: Makefile.in config.status
* Uses optional shell scripts $exec_prefix/lib/config.site and
$prefix/lib/config.site to perform site or system specific initializations.
* configure saves compiler output to ./config.log for debugging.
+* New file autoconf.m4 loads the rest of the Autoconf macros.
+* acsite.m4 is the new name for the system-wide aclocal.m4.
* Has the beginnings of a DejaGnu test suite.
** New macros:
* AC_VERBOSE pays attention to --quiet/--silent, not --verbose.
* AC_CHECK_FUNCS and AC_CHECK_HEADERS take optional shell commands to
execute on success.
+* AC_REMOTE_TAPE removed; it was too specific to tar and cpio.
** New utilities:
* autoscan to generate a preliminary configure.in for a package by
# Ones that have their own macros.
