--- Comment #4 from Ian Lance Taylor <ian at airs dot com> ---
What is different about 32-bit SPARC is not that it treats pointers and
integers differently, but that
struct { void *p; }
and
void *p;
are passed as arguments in two different ways. The former is passed by
invisible reference and the latter is passed directly. On many platforms they
are passed as arguments in exactly the same way.
