late stage due to the fact that link.h was copyright Sun Microsystems. This version of ld sync's us up with NetBSD's ld and supports compatablily with NetBSD's -[zZ] flags (which we had reversed). Compiling with this new ld will give you RRS warnings for libraries which do not contain .type infomation - these wsarnings are harmless and will go away as soon as you recompile your libraries (cd /usr/src; make libraries).
