configure: WARNING: cannot find a DTD for DocBook XML V4.2, you will not
be able to validate your documentation
configure: WARNING: check your XML_CATALOG_FILES environment variable

configure: WARNING: cannot find DocBook XSL stylesheets, you will not be
able to build the documentation
But this is erroneous because I have laboriously installed DocBook's XSL
many times. I traced the problem to the fact that autoconf was checking
specifically for version 4.2, and I have installed version 4.5, which is
the latest as of this writing. Bumping the version numbers in aclocal.m4
and running autoreconf fixed the problem. Patch attached.
