This is a generated file. It would appear the make target to build yacc.h hadn't run yet by the time the target that consumed the file ran.

I had a similar problem on Sunday. It wasn't yacc.h but some other file, I cannot remember which. It occurred during one of four buildworlds. Simply restarting the failed buildworld was enough to resolve it.

My hypothesis is a buildworld race. I wonder if some of the recent (over the last week or two) makefile changes exacerbated this issue.
