This is not a bug. ANSI C defines a thing called trigraphs for machines or
terminals that don't have some of the less common characters. 
Trigraphs are three character macro like devices that allow you to make
funny characters.  Ex.  ??= is #   ??( is [  ??! is |   and  ??' is ^ .
There are others.

6.0 is trys to be ANSI in every way it can.  Another difference between
5.1 and 6.0 that has given me compiler errors is the fact that the type
of a shift expression now is the same type as the left side of the expression:
(short_v << long_v) is of type short, in 5.1 it would have been a long.

You can still put your ??' in a printf, just type \?\?' or ?\?' .
