I haven't confirmed yet that this works in the msys2 environment on
Windows, although according to
, it supposedly shouldn't cause any issues with building under msys2 or WSL.
It appears all of the contents of this patch have been taken from
another patch, available at
, although its reasonable that the author of this patch would have come
up with it on their own since it is so simple. It would be reasonable
to give credit to Gilles Khouzam in the patch description, if the author
of this patch (Cyber Sinh) and Gilles Khouzam are not the same individual.
Also, Gilles's patch does more to get FFmpeg to build properly under
WSL, so just adding the file extension may not be sufficient to get
FFmpeg to build under WSL.
On a separate note, building under WSL, as opposed to msys2, seems
promising if only from a build performance perspective. According to
the blog post, it builds at least twice as fast under WSL than it does
