What should a compiler do with the comparison in this example:

    unsigned int a;

    a = 5;
    if (a > -1) ....

Since all of the possible values for a are positive, the comparison 
should always be true and the compiler should process this as though it
were written
    if (1)

Correct? Does the standard address this case?
