That's a reasonable theory.  Back when I worked on Amanda, we had a
--enable/disable-libtool automake conditional that would enable or
disable the use of libtool libraries and the corresponding .lo files.
Perhaps there's some error in one of the conditional branches that
causes double-compilation, and automake fails to detect it because of
the conditionals?
