Yes, new install directories.  You don't want "make install" to produce a 
tree with some files in the new locations and some in the old.

New makefile variables need adding everywhere.  Automake needs upgrading 
to 1.10 at the same time.

A number of local configure options (--with-datarootdir --with-docdir 
--with-htmldir) need removing everywhere since new autoconf has standard 
replacements for them.  The documentation needs updating to remove those 
options and reflect the standard replacements.

The local install-html support in automake-using directories (which those 
configure options are present to support) needs removing when upgrading to 
new automake with built-in install-html support.
