| // enabled in various Standard modes. This is a common source of breakage |
| // since the 'std' module will include all headers, so if something in a |
| // header fails under a standard mode, importing anything will fail. |
| |
| // This test fails on Windows because the underlying libc headers on Windows |
| // are not modular |
| // XFAIL: LIBCXX-WINDOWS-FIXME |
| |
| // Some headers are not available when these features are disabled, but they |
| // still get built as part of the 'std' module, which breaks the build. |
