The patch avisynth-input_v2.patch works fine for me, under Cygwin.

Platform is Cygwin 1.5.21, gcc 3.4.4, Avisynth 2.56.

Transcode test is:

$ ./ffmpeg -i 'C:\Program Files\AviSynth 2.5\Examples\Authors.avs' \
   -y output%d.png
FFmpeg version SVN-r6005, Copyright (c) 2000-2004 Fabrice Bellard

1) Static Cygwin
   make distclean; ./configure --enable-static --disable-shared \
  --enable-avisynth; make
   Builds OK.
   Transcodes AVS to PNG OK.

2) Shared Cygwin
   make distclean; ./configure --disable-static --enable-shared \
   --enable-avisynth; make
   Builds OK.
   Transcodes AVS to PNG OK.


make test fails, but exactly as if I don't use --enable-avisynth,
so this is an error not related to the patch.

I see there is already a avisynth-input_v4.patch, I will re-test it
this evening.
