The problem is that "ln" is emulated in MinGW by "cp", so you're
really attempting

cp -f \
/home/wzrlpy/src/FFMpeg-20060802-5893/ffmpeg/libavutil/avutil-49.0.0.dll \
"C:\Program Files/FFmpeg/lib/avutil-49.dll"

and that fails, because there is no
/home/wzrlpy/src/FFMpeg-20060802-5893/ffmpeg/libavutil/avutil-49.0.0.dll
