This is a serious problem for the free software community; it's forked itself. That is a serious _bug_ by design; their maintainers need to be spanked and then made to work out their differences. --Z _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
