Nice :)

Is that counted correctly? You count

/local/svn/kde/trunk/KDE/kdelibs/kjs/object.h:254: warning: 'virtual void 
KJS::JSObject::put(KJS::ExecState*, unsigned int, KJS::JSValue*, int)' was 
hidden
/local/svn/kde/trunk/KDE/kdelibs/kjs/function.h:97: warning:   by 'virtual 
void KJS::Arguments::put(KJS::ExecState*, const KJS::Identifier&, 
KJS::JSValue*, int)'

as two warnings, instead of one.

Well, do not disable them. Warnings could be grouped by the actual warning 
message, so that one can easily skip "deprecated", "unused parameter", 
or "virtual was hidden" messages.

To relativize the warning number, I counted 759 unique warnings (including 
warnings not issued by the C++ compiler) using this command:

grep warning:\  kdelibs-warnings.txt | grep -v warning:\ \ \ by | sort | 
uniq -c | sort -k 2 | sort -nrs > kdelibs-warnings-uniq.txt

See http://pastebin.com/m4bcdf27d for kdelibs-warnings-uniq.txt

If anyone wanted to dramatically reduce the warning count, she would start 
fixing those with the highest duplicates :)
