* Constants
*
* The following macros create constants of the types defined in
* <sys/int_types.h>. The intent is that:
* Constants defined using these macros have a specific size and
* signedness. The suffix used for int64_t and uint64_t (ll and ull)
* are for examples only. Implementations are permitted to use other
* suffixes.
*
* The "CSTYLED" comments are flags to an internal code style analysis tool
* telling it to silently accept the line which follows. This internal
* standard requires a space between arguments, but the historical,
* non-ANSI-C ``method'' of concatenation can't tolerate those spaces.
