A lot of code also assumes sizeof(int) == 4 and sizeof(long) == 4. Something's
obviously going to break, and I think compiler makers decided leaving
sizeof(int) == 4 would break less code than not (poeple use int more than
long). C99's [u]int[8|16|32|64]_t typedefs were made so you had standard
typedefs with gauranteed sizes and help ensure 32/64-bit compatible code
(MSVC has the internal types __int[8|16|32|64], but it was never part of any
standard, and C99's is more encompassing).
And yes, MSVC does have BYTE, WORD, DWORD, and QWORD, but these are always
unsigned, so you're out of luck if you need signed values.
