dnl APU_LIB_BERKELEY_DB(major, minor, patch, places, headers, libnames)
dnl
dnl Search for a useable version of Berkeley DB in a number of
dnl common places. The installed DB must be no older than the
dnl version given by MAJOR, MINOR, and PATCH. All of these
dnl arguments are allowed to be '-1', indicating we don't care.
dnl PLACES is a list of places to search for a Berkeley DB
dnl installation. HEADERS is a list of headers to try. LIBNAMES
dnl is a list of names of the library to attempt to link against,
dnl typically 'db' and 'db4'.
dnl
dnl If we find a useable version, set CPPFLAGS and LIBS as
dnl appropriate, and set the shell variable `apu_have_db' to
dnl `1', and apu_db_lib to the matching lib name, and apu_db_header
dnl to the header to use. Otherwise, set `apu_have_db' to `0'.
dnl
dnl This macro also checks for the `--with-berkeley-db=PATH' flag;
dnl if given, the macro will use the PATH specified, and the
dnl configuration script will die if it can't find the library. If
dnl the user gives the `--without-berkeley-db' flag, the entire
dnl search is skipped.
dnl
dnl We cache the results of individual searches under particular
dnl prefixes, not the overall result of whether we found Berkeley
dnl DB. That way, the user can re-run the configure script with
dnl different --with-berkeley-db switch values, without interference
dnl from the cache.

dnl APU_TRY_BERKELEY_DB(major, minor, patch, header, libname)
dnl
dnl A subroutine of APU_CHECK_BERKELEY_DB.
dnl
dnl Check that a new-enough version of Berkeley DB is installed.
dnl "New enough" means no older than the version given by MAJOR,
dnl MINOR, and PATCH. The result of the test is not cached; no
dnl messages are printed. Use HEADER as the header file to include.
dnl Use LIBNAME as the library to link against.
dnl (e.g. LIBNAME should usually be "db" or "db4".)
dnl
dnl Set the shell variable `apu_try_berkeley_db' to `yes' if we found
dnl an appropriate version installed, or `no' otherwise.
dnl
dnl This macro uses the Berkeley DB library function `db_version' to
dnl find the version. If the library installed doesn't have this
dnl function, then this macro assumes it is too old.
dnl NOTE: This is pretty messed up. It seems that the FreeBSD port of
dnl Berkeley DB 4 puts the header file in /usr/local/include/db4, but the
dnl database library in /usr/local/lib, as libdb4.[a|so]. There is no
dnl /usr/local/include/db.h. So if you check for /usr/local first, you'll
dnl get the old header file from /usr/include, and the new library from
dnl /usr/local/lib. Disaster. Thus this test compares the version constants
dnl in the db.h header with the ones returned by db_version().
