That seems an odd way to generate missing declarations. Missing headers may
lead to different code being compiled because of undefined macros, feature test
macros, pragmas, etc.
If the header is missing, then ignoring the error will produce exactly the same
result as commenting out the #include.
Anyway, not a bug.
