Re: pointers in different storage models

Hi, Mihael:

I think you also need to change this prototype so it looks like this:

    bool
    prop_object_equals_with_error(prop_object_t obj1_128, prop_object_t 
obj2_128,
        bool __ptr128 *error_flag)

Or define a typedef for "bool128p" such as:

	typedef void * __ptr128 bool128p;

and then change  the prototype to look like:

    bool
    prop_object_equals_with_error(prop_object_t obj1_128, prop_object_t 
obj2_128,
        bool128p *error_flag)

You could also use #pragma statements to turn on and turn off 128-bit 
pointers as the default, so for example, you could have 128-bit pointers 
as the default for all of the external function declarations, and then 
have another #pragma to switch to 64-bit pointers for all local 
varialbes internal to the routines.
