  61  * Constants
  62  *
  63  * The following macros create constants of the types defined in
  64  * <sys/int_types.h>. The intent is that:
  65  *      Constants defined using these macros have a specific size and
  66  *      signedness. The suffix used for int64_t and uint64_t (ll and ull)
  67  *      are for examples only. Implementations are permitted to use other
  68  *      suffixes.
  69  *
  70  * The "CSTYLED" comments are flags to an internal code style analysis tool
  71  * telling it to silently accept the line which follows.  This internal
  72  * standard requires a space between arguments, but the historical,
  73  * non-ANSI-C ``method'' of concatenation can't tolerate those spaces.
