If 19 is represented differently in binary on your platform than (leading zeros)10011, you are already quite screwed.

You might be thinking of character representation for the later example.

No, I was thinking binary 19. Does C say the implementation is going to be 1s complements, 2s complements or whatever?

Is there anything that says, for example, it can't be BCD?

Yes even though this is exactly why people want to use C now, to get exact binary behaviour.
