configure.in and build/*.m4 have to be updated first to latest autoconf (ugh)

aclocal.m4 not fully updated.  Could be a problem???

of version and then try -lsasl2 and -lsasl.  Make SASL code
conditional on SASL_VERSION_MAJOR, not HAVE_CYRUS_SASL.

Label some options as experimental
Change how configure prints defaults

configure.  Implementation is dependent upon autoconf internals.
Attempts to use AC_REVISION hammered by libtool bugs.  Will submit

	latest autoconf (from AnonCVS)
	aclocal from latest automake (from AnonCVS)
	libtool 1.3.3

one preprocessor macro instead of two.  Ran aclocal, autoconf,
autoheader to update derived files.  Modify util-int.c to use
CTIME_R_NARGS define and fallback to ctime() if not set.
Made LDAP_API_FEATURE_X_OPENLDAP_REENTRANT dependent upon result.

Teached autoconf to figure out how may arguments ctime_r expects.
Updated util-int.c to use this information.
