Обсуждение: pgsql: Change expand_subsys function so that it preserves the relative

Log Message:
-----------
Change expand_subsys function so that it preserves the relative order of
the files passed as argument.  This is desirable so that the dtrace rule
in src/backend/Makefile works.

Modified Files:
--------------
    pgsql/src/backend:
        common.mk (r1.4 -> r1.5)
        (http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/src/backend/common.mk?r1=1.4&r2=1.5)
