// On Windows, the filesystem silently strips trailing whitespace and dots
// from filenames, so the include succeeds. We should still emit a
// portability warning but no file-not-found error.

// Trailing whitespace: warn about non-portable path, but file is found.
#include "simple.h " // expected-warning {{non-portable path to file 'simple.h '; specified path contains trailing whitespace}}

// Trailing dots: warn about non-portable path, but file is found.
#include "simple.h." // expected-warning {{non-portable path to file 'simple.h.'; specified path contains trailing dot}}

// Correct path: no diagnostics expected.
#include "simple.h" // no-warning
