I applied the same fix that was applied to chown in trunk r77007 for 
lchown and fchown.  Could you test it on a platform where it previously 
failed?

The existing code might still have issues if there are platforms where 
uid_t and gid_t are unsigned but not the same size as a long as at the 
moment it merely casts and does not test to see that the values are the 
same as the patch you have supplied here.
