No.  Although its name would imply otherwise, that test checks the 
alignment of *int* fields within structures.  I didn't change that 
fact.  All I did was to make the libffi type specifiers accurately 
reflect the types of the parameters and return values.

My understanding is that valid test cases should never be changed.  If 
one wants to test for something different, a new test case should be 
written.  The intent of my patch was to fix internal inconsistencies in 
the test cases with out changing what they were testing for.  I agree 
that it would make sense to add tests that check passing of fixed width 
integers, but that is not what this patch does.
