I prefer to describe these as 'incompatibilities' rather than 'problems'.
Why? MSVC currently implements a subset of C99. This subset differs from the
subset of C99 that is currently used by FFmpeg.  These incompatibilities are
*not* restricted to MSVC; older and discontinued compilers will suffer from
these incompatibilities too.

This is unwarranted, and would make the resulting patchset harder to maintain.
There are tools amd scripts that can perform the transformation automatically.
Search the web for "a2i".
