I have compiled a patch to improve support for Objective C.

I am not sure where to add the following keywords so they live in
c-other-decl-kwds for now. Please review the patch. Thanks.

  1. @property
     : @property (attributes) Type propertyName;
  2. @dynamic
     : @dynamic aProperty, bProperty;
  3. @synthesize
     : @synthesize aProperty, bProperty, cProperty=_ivar;
  4. @compatibility_alias
     : @compatibility_alias AliasClassName ExistingClassName;
