I like the idea (always liked it) to fix all these warnings - I guess some of 
my patches were lost...

However you define "false positive", they simply pollute the screen and when 
searching for real issues, you have to read through again and again. In this 
meaning, there is no false positive - except the compiler has a bug (the clang 
analyzer really finds some (cough) interesting things).

I once made a patch that fixed those 'const' warnings when compiling with -
DDEBUG (triggers selftest code). But I think it was not applied :-(

However, good idea, and I try to find some time !
