No, this message should be outside the check so that the builder always knows what happened, independent of what configure flags they passed. Typically, people start by not passing any flags, and it is helpful to explicitly log that a feature was not enabled. Even if you pass the --enable flags, it is comforting to get an explicit confirmation that the feature you asked for is enabled. - James ----------------------------------------------------------- This is an automatically generated e-mail.
