If OSF/1 only needs the pointer to the struct sigcontext, and if all arguments are 64 bits wide (respectivly passed in places where 32 bit values don't cause a tighter placement of the next argument), we could in fact use both of (int, int, struct sigcontext *) [Old FreeBSD style] and (int, siginfo_t *, struct sigcontext *) [POSIX SA_SIGINFO] without breaking binary compatiblity to OSF/1. Thus, it would be doable to drop the old FreeBSD style, except when OSF/1 somewhere uses the integer second argument (which I doubt, this is FreeBSD-specific, IMHO).
