maybe what happened was that the original author also tried several

I've added a missing ) behind .l:
u.u_dirp.l = (caddr_t) ((long) (((saddr_t) (uap->linkname).l)) &
0x7F00FFFF);
And I've got:
"sys2.c":305: warning: struct/union or struct/union pointer required
"sys2.c":305: operands of CAST have incompatible types
the author faced a difficult to parse
expression and broke it with an auxiliary variable,
saddr_t aux;
aux.l = (caddr_t) uap->linkname;
u.u_dirp.l = (caddr_t) ((long) aux.l & 0x7F00FFFF);
or some such.
