5-CURRENT build errors

[Eric Timme]

In my case this is an attempt to go from a fresh 5.2.1 install to 
5-current. Could you recommend a date to sync to as a stepping stone to 
5-current?

I found others with similar problems dating from early February, and a
post
recommended rebuilding yacc from the source tree, installing, then trying 

another buildworld. I'm attempting that as we speak, I'll know in about 6 

hours if it worked.
