[FFmpeg-devel] [PATCH] configure: enable warnings for shadowed variables

[Timo Rothenpieler]

These can easily lead to incredibly confusing errors, and should
practically never happen.
I'd have loved to make this a -Werror even, but sadly there is way too
many instances in the codebase right now that first needs to be weeded
out.
