FreeBSD 4.x, no? My FreeBSD 3.4 code still uses

	int
        getsockname(int s, struct sockaddr *name, int *namelen)

This needs to be done thru autoconfig, I think. Likely, the easiest would
to mimic what is being done already with other data type changes already
in Mash or in other packages -- perl's autoconfig for example plays games
like this.
