I think you get a small number but anyway.
The main reason this wasn't tested lately was that last gcc
showed a larger number of invalid warnings.

What does "grep HAVE_LIBC_MSVCRT config.h" show for you?

fd is signed here, I doubt this can be silenced.

Does changing the third argument of av_image_copy() in libavutil/imgutils.h
into "const uint8_t * const src_data[4]" silence anything?
(Only hwcontext_d3d11va.o testing required, breaks imgutils.o compilation)

I wonder if this is a bug...
