Hello,

bootstrapping a checkout of the emacs25 branch fails for me.  master
builds fine.

Here is what I did: I checked out the emacs-25 branch, I have a clean
worktree.  Then ./autogen.sh, ./configure, make bootstrap.

Here are the final lines of output that "make bootstrap" gave before it
died:

Minor issue: after that had failed, I had to delete several lock files
by hand.

I'm reporting from the same environment with a master build.


Thanks,

Michael.
