This macro tries to find Berkeley DB C++ support. It honors MINIMUM-VERSION if given.

If libdb_cxx is found, DB_CXX_HEADER and DB_CXX_LIBS variables are set and ACTION-IF-FOUND shell code is executed if specified. DB_CXX_HEADER is set to location of db.h header in quotes (e.g. "db3/db_cxx.h") and AC_DEFINE_UNQUOTED is called on it, so that you can type

  #include DB_CXX_HEADER

in your C/C++ code. DB_CXX_LIBS is set to linker flags needed to link against the library (e.g. -ldb3.1_cxx) and AC_SUBST is called on it.

when specified user-selected spot (via –with-libdb) also sets

  DB_CXX_CPPFLAGS to the include directives required
  DB_CXX_LDFLAGS to the -L flags required
