The patch looks like it should work fine, I guess John Paul Adrian Glaubitz is
going to test it soon. But I wonder whether the determination of alignment is
in types.cc really needed, as user-specified alignment directives can only make
alignment stricter. So always passing 4 to implicit variable should do no harm
and keep the code simpler.
