From the AT&T SVID (System V definition), "The function <malloc> returns a pointer... suitably aligned for any use". From the SunOS manual page, "malloc() returns a pointer to a block... which is appropriately aligned" (Currently I don't have access to true BSD). However, it is important still to use rtypalign() and force the types to be those for C rather than for internal Informix use.
