Should be fixed now. That was a last minute change when I realize that 
it doesn't build on 8.2. I didn't rechecked it on 9/10 after the fix was 
applied. Apologies and thanks for the hands up.

Btw, it builds fine to me on -current amd64 with MAKE_JOBS_SAFE=yes, 
should I add this knob to Makefile?
