[sane-devel] error building using --enable-static

[Chris Bagwell]

I fixed the kvs backend symbol issues and committed them.

Also, I believe I have a fix for jpeg symbols.  I think its just a
linking ordering issue.  At least I got it working by hand editing the
frontend/Makefile and moving the libraries with missing symbols to
later in line of saned_LDADD and scanimage_LDADD.

I do not have the older versions of autofoo packages installed and
I'll reluctant to submit large configure and Makefile.in file updates
at this stage.

If someone has older autofoo installed and can check in just
frontend/Makefile.am and frontend/Makefile.in change, here is
suggested patch (I notice that liblib.la is in two different orders.
May need to move one of those to later as well):
