Yes, I do something like that in every package for which I make releases, these days. There is a separate clause in configure.ac where we arrange to remove troublesome warning options from the global list to form the CFLAGS options used for gnulib proper: AC_SUBST([GNULIB_WARN_CFLAGS]) and sometimes also (e.g., in grep) where we do similar for gnulib tests: AC_SUBST([GNULIB_TEST_WARN_CFLAGS])
