I've just installed the attached fix which takes the
different approach.  I gave up generating a list of TIT and
MISC-DIC sources, but could eliminate kludgy code for
avoiding parallel make problems.

I changed only leim/Makefile.in, and tested it only with GNU
Make.  I'd like to ask main maintainers of the other systems
to change makefile.nt and makefile.w32-in accordingly (and
test them).
