  Using subdirectories unfortunately opened up a can of worms.  In order to prevent object name conflicts, it is necessary to use the subdir-objects automake directive, but it simply doesn't work right on some of the versions of automake we still have to support.  Another option would be to add a separate Makefile.am file to each subdirectory, but that requires maintaining a completely different set of build rules for each one.  Fortunately, however, we're in the 21st century now, so we can use filenames longer than 8.3.
