 dnl Database support
-dnl <mdiers@logware.de>
 dnl We do not necessarily have to have libdb/lib(g)dbm for DB/(G)DBM support.
 dnl On FreeBSD, both DB and DBM are part of libc.
-dnl Note that unless support for DB/(G)DBM is explicitly disabled, we always
-dnl want to check for libdb/lib(g)dbm. Also note that libc will not be
-dnl checked if we have the libraries.
-dnl If support for DB/(G)DBM is requested, but we neither have libdb/lib(g)dbm,
-dnl nor does libc implement it, we are a bit lost :)
