// We're building as C, so this test doesn't work when building with modules.
// UNSUPPORTED: modules-build

// GCC complains about unrecognized arguments because we're compiling the
// file as C, but we're passing C++ flags on the command-line.
// UNSUPPORTED: gcc

// Test that the C wrapper headers can be included when compiling them as C.

// NOTE: It's not common or recommended to have libc++ in the header search
// path when compiling C files, but it does happen often enough.
