# Check silent-rules mode, with many languages at once.
# This test partly overlaps with other silent*.test, but it serves as
# a stress test by using many different languages at once -- so don't
# remove this test script.
# This test should work with generic compilers; keep it in sync with
# sister test 'silent-many-gcc.test', which requires the GNU compilers
# and forces the use of gcc depmode.
