You're using a slightly outdated version of gcc, cause 'clr r11' followed by 'clr r12'

It does not... Actually this is a good thing to use 'lint'. It helps beginners to find many errors before first compile attempt. For example this will complain about unefficient cast ;) Cheers, ~d > > M. > > > ------------------------------------------------------- > This SF.Net email is sponsored by BEA Weblogic Workshop > FREE Java Enterprise J2EE developer tools! > Get your free copy of BEA WebLogic Workshop 8.1 today. > http://ads.osdn.com/?ad_id=4721&alloc_id=10040&op=click > _______________________________________________ > Mspgcc-users mailing list > Mspgcc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/mspgcc-users
