that made ccprintf and friends work, turn it into a normal function (though it still has a slightly strange implementation.) All instances of variadic macros are not yet removed, but I know how, and it will happen. One side effect of this new implementation is that a cprintf statement can now only have 16 parameters, though it's easy enough to raise this number if needed. --HG-- extra : convert_revision : 85cb3c17f8e2ecf9cd2f31ea80a760a28ea127a7
