Subject: [PATCH] * aclocal.m4 	Added several macros and restructures to allow
 for testing of 	which dbm type to use and to override with 
 --with-kdb-db=DBM 	--with-aname-db=DBM 	Added USE_ANAME macro to
 specify a module requires the aname db. 	USE_KDB5_LIBRARIES now checks
 the --with-kdb-* flags.
