Added comment. Please check this! * EOAccess/EODatabaseContext.m include NSObject+GNUstepBase.h avoid Enumerator exception. * EOAccess/EOUtilities.m split line into two * EOAccess/EOAdaptorChannel.h/m unsigned -> NSUInteger * EOAdaptors/PostgreSQLAdaptor/PostgreSQLChannel.h removed _describeResults * EOAdaptors/PostgreSQLAdaptor/PostgreSQLChannel.m include NSObject+GNUstepBase.h added numberOfAffectedRows attribute naming in raw rows fixed updating fixed unsigned -> NSUInteger git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/gdl2/trunk@30586 72102866-910b-0410-8b05-ffd578937521
