Additional warnings (-W) revisited

[Joerg Mayer]

Hello,

a year or more ago I started an attempt to turn on additional warnings
with gccs -W switch. The amount of additional warnings created made any
warnings useless (the current count is >2700). I've just thought about
the problem again and come up with a divide and conquer approach:
Why not turn -W on and disable the additional warnings on a per directory
basis? The idea is to turn on the additional warnings and then disable
them on a per directory/type basis by putting a file into each directory
turning off one or both of the additional warnings that occur very often
(signed/unsigned comparisons and unused parameters/variables). If both
warnings should be shown in a directory, the file may be removed.
I've attached an example patch and the initial look of the .nowarn file.
What do you think of the idea in general and this particular solution?

   Ciao
                Jörg

I found out that "pro" means "instead of" (as in proconsul). Now I know
what proactive means.
