I don't think so. While there may be false "uninitialised" warnings  
(because the compiler simply missed the initialisation somehow),  
every use of an uninitialised variable is an error.

However, not every case of an if-expression which can evaluated at  
compile time is an error. I even don't think the majority is.

These constructions can also be used instead of ifdefs, even though  
ifdefs are probably also more often used. Using if's instead is   
however not wrong imho.
