Support Exportable modules (like Oberon '*'). As an output, create a DLL

[steven-r]

The follwing will create a DLL instead of an executable...

MODULE export;

PROCEDURE x*;
BEGIN
END x;

BEGIN
  (* init code *)
END export;

The code will emit one external static function ('x'). The init code will be executed as part of system initialization.

Tasks:

• Grammar adaptions (* on module, * on type, const, var name)
• Handle type/var/const .Exportable flag
• Handle proc .Exportable flag
• check logic (const as exportable, module not marked)
• IMPORT statement
• MSIL code generation
• prevent parameters to be marked as exportable (i.e. global only)
• Command line addons
  - [ ] Generate warning in case MODULE is marked as exportable and no type/var/const/proc is marked
