When running the tests without pre-compiled headers (--disable-libstdcxx-pch), the test fails, because the feature testing macro (FTM) isn't defined yet. This commit moves checking the FTM to a dedicated file (version.cc) that's run without PCH. libstdc++-v3/ChangeLog: * testsuite/20_util/function_objects/not_fn/nttp.cc: Move test of feature testing macro to version.cc * testsuite/20_util/function_objects/not_fn/version.cc: New test.
