I like this solution.  (Note that it may be approximated with current tools by
unprotoizing and then running lint.)

The important bit is to get the feature implemented and make it optional.
Deciding which setting should be default is a minor issue, and in any case it
can be tuned for your local site.  (I usually run gcc with -Wall -Wcast-qual
-Wwrite-strings, myself.)

Since floating-point constants have type "double" by default, it suffices to
use "3.0" (or even "3.", but I consider it good style to always have a digit
on each side of the decimal point).
