The warning in c_common_post_options for -Wmissing-format-attribute 
without -Wformat will need rewording, and "warning (0," in the patch 
should use OPT_Wmissing_format_attribute instead of 0.

The digest_init change is OK for mainline (I think it will also help in 
fixing other bugs to have such initializations pass through 
convert_for_assignment).  The C++ front end changes to add extra 
attributes are probably OK but it's not for me to approve them.  The 
remaining changes to add the new feature (with the changes I mention 
above) are OK for 4.2 but it's the RM's call for 4.1.
