1448         More work on char, short, int sized data.  Add both
1449         compare_double_and_swap_double and compare_and_swap_double.
1450         Typically each platform will provide at most one of these.
1451
1452 2004-07-02  Ranko Zivojnovic
1453         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1469         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1470         compiler on PA_RISC and IA64.
1471

1486
1487
1488 Started sometime after version 0.4 release.  Currently the format is
1489 informal.  Eventually should become more GNU-like.
