I am not convinced that exactly is a very good idea. I would expect that 
with plugins, we'll have significantly more attributes. I don't know if 
having a really big CFLAGS (in Linux Makefile parlance) is a good idea.

The proposed underscore notation is quite simple, and suggest a notation 
to separate the important attributes (those handled by GCC core) from 
the other ones.

A more sophisticated variant would be to have every attribute belonging 
to some attribute class, and have Wno-attributes=attributeclass but I 
feel that is too complex!

Regards.
