[ns] ns-2.28 validation problem

[Chen, Chun-cheng]

Hi:

    I got the message after validating ns-2.28 on FC3. Can anyone let me =
know if this is what it should happen?=20
All test output agrees with reference output.
These messages are NOT errors and can be ignored:
    warning: using backward compatibility mode
    This test is not implemented in backward
compatibility mode
 =20
validate overall report: some tests failed:
     ./test-all-newreno
to re-run a specific test, cd tcl/test;
./test-all-TEST-NAME
Notice that some tests in webcache will fail on
freebsd when -O is turned on.
This is due to some event reordering, which will
disappear when -g is turned on.
