nofile:0:0: information: The checking of the file will be interrupted because
there are too many #ifdef configurations. Checking of all #ifdef
configurations can be forced by --force command line option or from GUI
preferences. However that may increase the checking time. For more details,
use --enable=information. [toomanyconfigs]
