Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Tue May 31 21:05:29 2016 -0400

    Build with builddir != srcdir
    
        * autogen.sh: chdir to $srcdir to create configure, then back to
          $builddir to use it.
        * libbalsa/imap/Makefile.am: provide path to
          libimap-marshal.list.
