/* Purpose: This module implements the Objective-C 4.0 language.
compatibility issues (with the Stepstone translator):
- does not recognize the following 3.3 constructs.
@requires, @classes, @messages, = (...)
- methods with variable arguments must conform to ANSI standard.
- tagged structure definitions that appear in BOTH the interface
and implementation are not allowed.
- public/private: all instance variables are public within the
context of the implementation...I consider this to be a bug in
the translator.
- statically allocated objects are not supported. the user will
receive an error if this service is requested.
