Even after this change, the build still fails on a later file:

src/libavutil/hwcontext_d3d12va.c:74:13: error: no previous prototype for 
function 'av_d3d12va_map_sw_to_hw_format' [-Werror,-Wmissing-prototypes]
    74 | DXGI_FORMAT av_d3d12va_map_sw_to_hw_format(enum AVPixelFormat pix_fmt)
       |             ^

There's no declaration of this in any header - so please either make it 
static or ff_ prefixed, or add it to a header with the declaration visible 
at the function definition.
