This request is certainly valid, though it should have the lowest 
priority, as far as I am concerned. It is just about too complicated 
to figure out whether we are on a codepath that isn't taken due to 
a particular template argument, or whether the code is really _never_ 
reachable (in which case we would like to have the warning). 
 
As for the argument of system and/or third party libraries: if this is 
a concern of yours, then having the include path indicate that this 
is a system header is the right choice (I think the flag is -isystem instead 
of -I). I don't see any other way than special casing these things this 
way. 
 
I doubt anyone will find time to "fix" this properly near or mid term...
