# These chained rules could be (and used to be) single rules using pipes or
# could even --- if you dare to --- use the `mig' shell script, but it's
# convenient to be able to explicitly make the intermediate files when you want
# to deal with a problem in the MIG stub generator.

# TODO.  Get rid of the following six rules and the lib_dep_tr_for_defs.a
# machinery (see Makefrag.am and i386/Makefrag.am).
