Sometime between revision 160389 and revision 160448,
testsuite/objc/compile/compile.exp started to use a new set of options for
overy test in testsuite/objc/compile/compile.exp, using -fnext-runtime
instead of -fgnu-runtime, thus adding 5 tests * 6 option compinations,
i.e. 30 new expected passes to the test results, for a default configuration
bootstrap/regtest on i686-pc-linux-gnu.  This is still the case at
revision 160461.
Running a bootstrap/regtest on i686-pc-linux-gnu with the configure option
--enable-build-with-cxx, I do not see these new test variants, and thus 30
fewer expected passes.

With the old trunk, or with the new trunk configured with
--enable-build-with-cxx, I see there is a test of -fnext-runtime at
the start of running compile.exp, which fails:

Using the following runtimes: -fgnu-runtime

With the new trunk configured without --enable-build-with-cxx, this test
appears to succeed:
