I can't seem to fix this in a timely manner.  I tried something like
this in Makefile[.in] but it isn't always run:

exports.c:
        @bldit="0" ; \
        echo "what to do? " ; \
        if test -f exports.c ; then \
            echo "looking for newer headers" ; \
            headers="`find $(top_srcdir) -name '*.h' -newer
        exports.c`" ; \
            echo "headers $$headers" ; \
            if test -n "$$headers"; then \
                echo Found newer headers.  Will rebuild exports.c ; \
                bldit="1" ; \
            fi ; \
        else \
            bldit="1" ; \
        fi ; \
        if test "$$bldit" = "1" ; then \
        $(AWK) -f $(top_srcdir)/build/make_exports.awk $(EXPORT_FILES)
        > $@ ; \
        fi
