I poked around in the alpha4 tarball and didn't find clock skew.
What I found out was that there's some fundamental fuzzy thinking
in the new docs build process:

* install-html depends on html depends on $(GENERATED_SGML)

* $(GENERATED_SGML) is removed by make clean, therefore also by
make distclean

Ergo, this type of failure is *guaranteed* when trying to build
from a distribution tarball.  This needs to be rethought.

It might be sufficient to not clean $(GENERATED_SGML) except in
make maintainer-clean, but I'm not convinced that's a nice solution.
