AX_BERKELEY_DB([MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
This macro tries to find Berkeley DB. It honors MINIMUM-VERSION if given.
If libdb is found, DB_HEADER and DB_LIBS variables are set and ACTION-IF-FOUND shell code is executed if specified. DB_HEADER is set to location of db.h header in quotes (e.g. "db3/db.h") and AC_DEFINE_UNQUOTED is called on it, so that you can type
in your C/C++ code. DB_LIBS is set to linker flags needed to link against the library (e.g. -ldb3.1) and AC_SUBST is called on it.
when specified user-selected spot (via –with-libdb) also sets
DB_CPPFLAGS to the include directives required DB_LDFLAGS to the -L flags required
