 Hello,

 I've created https://github.com/let-me-illustrate/lmi/pull/200
corresponding to xanadu/autoupdate-2.71 branch in your local terminology
containing the fix this problem, similar one for libxml2 and also many
related problems in lmi's own configure.ac which don't appear in your build
but which were annoying me.

 The changes in this branch include updates of both libxml2 and libxslt to
the latest versions: for the former this was done because it already
includes the fix to configure.ac and I thought it would be better to use it
directly instead of just cherry-picking it into our own branch. For the
latter it was mostly done just for consistency because it still doesn't
fix this warning even in the latest version (but I've submitted my trivial
fix for the inclusion). I think that in either case updating is worth it as
there are many bug fixes in both libraries and even though I don't know if
any of them could affect lmi, it still seems better to have them rather
than not to. If, however, you disagree, I could redo this PR to only
include just the changes to configure.ac that we need.

 Please let me know if you'd like me to do this or change this PR in any
other way.

 Thanks,
VZ
