New Revision: 217146
URL: http://svn.freebsd.org/changeset/base/217146

Log:
  On 32 bit architectures define (u)int64_t as (unsigned) long long instead
  of (unsigned) int __attribute__((__mode__(__DI__))). This aligns better
  with macros such as (U)INT64_C, (U)INT64_MAX, etc. which assume (u)int64_t
  has type (unsigned) long long.
  
  The mode attribute was used because long long wasn't standardised until
  C99. Nowadays compilers should support long long and use of the mode
  attribute is discouraged according to GCC Internals documentation.
  
  The type definition has to be marked with __extension__ to support
  compilation with "-std=c89 -pedantic".
