Let me second this. Please note that in case you implement int as 64-bit,
then there will be either no 32-bit or no 16-bit integer type (at all), as
there's only the short which is in between char ant int; hence, well, there
will be a kind of problem with some typedefs from <stdint.h>: either
int16_t/uint16_t or int32_t/uint32_t will actually have a size different
from what the name suggests, so you'll run into a trouble with
reading/analysing data in binary formats.
