Yes, but only slowly, over time, as they read the manual in desparation.  :-)

I agree that the warning shouldn't be in -Wall, but I think we could do
a better job of educating our users about the GCC features which are not
as well-known.  Non-Wall warnings seem to fall into this category.

No, I don't have any immediate ideas on how to do this.  ("GCC's Feature
of the Week for this week is:  Warnings Not Included In -Wall"...)
