The test continues to pass.
I ran it with gcc 9.4, 10.3.1 and 11.3.1 on somewhat latest Ubuntu/Fedora.
There is also this comment in gdb.exp already:

    # Some C/C++ testcases unconditionally pass -Wno-foo as additional
    # options to disable some warning.  That is OK with GCC, because
    # by design, GCC accepts any -Wno-foo option, even if it doesn't
    # support -Wfoo.  Clang however warns about unknown -Wno-foo by
    # default, unless you pass -Wno-unknown-warning-option as well.
    # We do that here, so that individual testcases don't have to
    # worry about it.

That said, I just tested it again with the latest Intel compilers. And GDB only
adds the "additional_flags=-Wno-unknown-warning-option" for clang, not
for icx/icc. I will write a new patch for that soon. But that is a separate
issue.
