[ofw] weird build issue

[Tzachi Dar]

I'm not sure what the exact problem, but I guess it is related to the
__ptr64 issue.

Please note that  ib_open_al() is defined as:

ib_api_status_t
ib_open_al(
		OUT			ib_al_handle_t* const
ph_al )

And ib_al_handle_t is defined as: 
typedef struct _ib_al* __ptr64			ib_al_handle_t;

In any case, I usually add the following pragma:

#pragma warning(disable: 4244 ) 

And just forgets about the whole issue.

Thanks
Tzachi
