Even if manages to build, the changes from AVSC_INLINE to
AVSC_API for those functions in the header will cause 2.5 to crash
if someone tries using it.  Reimplemented versions of those
functions would have to be added to the compat header (and as
I mentioned on the mail for the 2.5 drop patch, it'd require
navigating potential license potholes, and for 2.5 it just really isn't
worth it).

The ideal solution per patch #4 would be to figure out why the exact
same headers trip -Werror=implicit-function-declaration in FFmpeg
while they don't in Libav.  Somehow I doubt it's only because of
Libav's use of check_header in the --enable-avisynth configure check.
