Warning usage

["Daniel Walter" <d2walter@xxxxxxxxxxx>]

I have recently upgraded to a newer GCC compiler and have received a lot of 
new warnings. Many of these warnings are great and have found bugs that went 
undetected in my software for many years. Thank you GCC developers. 
Unfortunately some of these new warnings seem to be coding style dependent 
or not reasonably usable with the code base that I have.  This has caused me 
to turn off some warning options that in the past have been very helpful.

On other compilers, I generally start by setting the warning level at the 
highest value and making all warnings errors. From there I either fix the 
code as possible or pragma off warnings based on the responses from the 
compiler. I have tried using this strategy with GCC and I have run into two 
problems.
1. The GCC warning messages do not tell me which warning options I need to 
turn off either with compiler switches or pragmas.

2. When I find a compiler switch to turn off a warning, it generally seems 
to turn off a group of related warnings rather than one very specific 
warning. I am concerned this means that I am losing a lot of very useful 
warning information.

Is there an alternate strategy to making the most of warning information in 
GCC?  Any ideas on a way to find which warning options I need to turn off 
based on the warning messages would also be useful.
