Are you thinking of users using -Wall but not -W (and not expecting this
warning), or -W but not -Wall (and wanting this warning)?
(As my currently preferred warning options to use with 3.4 for general
purposes are -Wall -W -Wstrict-prototypes -Wmissing-prototypes
-Wold-style-definition -Wshadow -Wpointer-arith -Wcast-align -Wcast-qual
-Wwrite-strings -Wredundant-decls -Wnested-externs -Wmissing-noreturn
-Wformat-security -Wmissing-format-attribute -Winit-self, I tend to think
of moves between -Wall and -W as simply being bug fixes, making the
warnings follow more closely the definition of -Wall, rather than of
greater significance in changing user expectations, in particular assuming
that if -W is used then almost surely -Wall is as well.)

These look like reasonable descriptions to go somewhere on the web pages
