>> documentation states that:
>>
>> The return value is of type @code{INTEGER(n)}, where @code{n} is the
>> size (in bytes) of a memory address on the target machine.

>> So, I propose to change the gfc_trans_intrinsic_loc function to  
>> that its result is fold_convert'ed to the right integer type. I  
>> plan to commit the following patch on mainline next week-end  
>> unless someone objects.

>> Regtested (with Andrew's patches) on i686-linux.
