* AC_CONFIG_SUBDIRS to recursively configure a source tree.
* AC_CHECK_TYPE, which checks whether sys/types.h defines a given type.
* AC_TRY_LINK, which obsoletes AC_COMPILE_CHECK.
* AC_MSG_CHECKING and AC_MSG_RESULT to print test results, on a single line,
whether or not the test succeeds. They obsolete AC_CHECKING and AC_VERBOSE.
configure --verbose no longer has any effect.

* AC_PROG_INSTALL looks for install.sh in the directory specified by
AC_CONFIG_AUXDIR, or srcdir or srcdir/.. or srcdir/../.. by default.
* AC_DEFINE no longer prints anything, because of the new result reporting
mechanism (AC_MSG_CHECKING and AC_MSG_RESULT).
* AC_VERBOSE pays attention to --quiet/--silent, not --verbose.
