Why? I use int or short as "at-least-16-bits", long as
"at-least-32-bits" and long long (or a typedef if I have to support
VC) for "at-least-64-bits". I never use built-in types as overlays
for byte arrays, so I never need exact-sized types. Instead I use
unsigned version of all types and bit shift, binary "and" and binary
"or" to convert from byte array to number and back. Keeps my code
portable with ease and without unnecessary #ifdefs.
