CVS Head parser error?

I got following with CVS Head parser. I'm using bison 2.1 and flex
2.5.35. Am I missing something?

Sorry for noise. I regenerated scan.c and gram.c and now everything
works fine.

Hmm, are you sure that scan.c got remade?  I didn't check in detail, but
the errors look a bit like what would happen if the older scanner code
got recompiled against current headers.  I'd try "make maintainer-clean"
and start over before investing additional thought.
        regards, tom lane
