1213         More work on char, short, int sized data.  Add both
1214         compare_double_and_swap_double and compare_and_swap_double.
1215         Typically each platform will provide at most one of these.
1216

1251
1252
1253 Started sometime after version 0.4 release.  Currently the format is
1254 informal.  Eventually should become more GNU-like.
