That's what I said: run those before saying "make".  You _must_ force
configure re-run, because some of the files I changed affect how Emacs
is configured.

Are you saying that you still run autogen.sh and configure by hand,
and only after that run "make"?  That's unnecessary.

Or maybe you are building outside of the source tree?  In that case, I
don't know what you should do.
