Why isn't that obvious? It is well known that gettimeofday() is an expensive 
function, not only in mintlib. But there isn't a real portable alternative to 
it.

That is nonsense. Why don't you warn about using fopen then? It is also slow 
compared to other functions. The compiler shouldn't warn about usage of 
functions, when it can't provide alternatives.
