Ah! I read that as pointer to aggregate :-P
For the record, what is TPF ?
One of IBM's s390x operating systems. ../gcc/configure --target=tpf
So two different sized pointers to aggregate types will also have a
problem?
Nope, you misread the test:
/* Changes in machine mode are never useless conversions unless we
deal with aggregate types in which case we defer to later checks. */
if (TYPE_MODE (inner_type) != TYPE_MODE

That seems to be happening, yes, but there are other checks
that might let differing modes through...
