I think that's a *great* idea!

Personally, I don't care for all the methods that have been proposed on 
this thread that "hide" the manipulation of SREG (various macros, etc.), 
because of the very reason that they can be too easily be the causes of 
some bad behaviour unless someone is vigilant about using them. I 
generally prefer to be explicit about it.

*But*, if there is a reasonable way to have the compiler enforce good 
behaviour, such as the "critical" function attribute proposed above, 
then I think that beats out all other methods.

My $0.02.
