 Hi,
 
 this warning is intentional. According to the C standard the sequence
 "??)" is replaced with "]" in the very early preprocessing stage
 (even within strings). gcc doesn't follow the standard here unless -pedantic
 is specified but warns the user about this fact. This report should be
 closed.
 
     regards  Christian Ehrhardt
