Something like it... you just have to ensure there is enough space at the
end (i.e aligning requires that there is 1-3 bytes more space for the data).

Also, maybe better (or worse!) is (char *)(((int)address + 3) & ~3),
assumed that sizeof (char *) == sizeof (int).

This latter version seems to compile...

... this too: (char *)((int)((char *)address + 3) & ~3));, but that is not
any better (in sizeof comparisons...).
