the purpose is to refactor the function phpbb_version_compare in order to check if at least also the files (constants.php) are accordingly to the DB's config['version'].
Gives a more constructive way to check, at least, if we are allowing to install something onto a not ready to be used Board that gives the supporters more troubles than nothing else, nonetheless.
Making it mandatory the ext.php for extensions isn't, IMO, a bad idea.. also.
Comments and suggestions are welcome.
Thanks.
