+ Work around the Solaris 10 ACE ACLs ABI change.
+ * lib/acl-internal.h (acl_nontrivial, acl_ace_nontrivial): Don't
+ declare if ACL_NO_TRIVIAL is present.
+ (ACE_ACCESS_ALLOWED_ACE_TYPE, ACE_ACCESS_DENIED_ACE_TYPE,
+ NEW_ACE_OWNER, NEW_ACE_GROUP, NEW_ACE_IDENTIFIER_GROUP, ACE_EVERYONE,
+ NEW_ACE_READ_DATA, NEW_ACE_WRITE_DATA, NEW_ACE_EXECUTE): New macros.
+ * lib/file-has-acl.c (acl_nontrivial, acl_ace_nontrivial): Don't
+ define if ACL_NO_TRIVIAL is present.
+ (acl_ace_nontrivial): Detect whether the old or new ABI is in use,
+ and use the current ABI.
+ (file_has_acl): Use same #if condition as elsewhere.
+ * lib/set-mode-acl.c (qset_acl): Detect whether the old or new ABI is
+ in use, and use the current ABI.
+ * doc/acl-resources.txt: More doc about newer Solaris 10 versions.
+ Reported by Jim Meyering.

+ ACE_OTHER macro replaced with ACE_EVERYONE macro
+ ACE_OWNER, ACE_GROUP changed their values(!)
+ ALLOW, DENY macros removed(!)
