Regarding: http://gcc.gnu.org/onlinedocs/gcc-3.2/gcc/Function-Attributes.html#Function%20Attributes
When using an attribute that take parameter arguments, such as the format attribute, one needs to start counting parameters at *2* in C++ because (i'm assuming here) 'this' (the current object's address) is argument 1.
This took me a while to figure out why I kept getting "error: format string arg not a string type", but it seems to work now.
