I don't think so. Apart from dynamically typed languages which need to store the type with the value, it's always 1 byte, and that doesn't depend on architecture (excluding ancient or exotic architectures) or optimisation flags.
Which language/architecture/flags would not store a bool in 1 byte?
You know that depending on what your code does, the same C that people are talking upthread doesn't even need to allocate memory to store a variable, right?
How does that work?
I think he's talking about if a variable only exists in registers. In which case it is the size of a register. But that's true of everything that gets put in registers. You wouldn't say
uint16_tis word-sized because at some point it gets put into a word-sized register. That's dumb.
