Build error while compiling ffmpeg on cygwin with libx264

Question

configured ffmpeg(0.6.1) with below command (with x264-snapshot-20101228-2245 snapshot) with Gcc version : gcc (GCC) 4.3.4 20090804 (release)

./configure --enable-shared --disable-static --enable-pthreads --enable-libx264 
--enable-gpl --disable-doc --enable-memalign-hack 
--extra-ldflags="-L/usr/local/lib"

and after that, "make" command is giving below error.

I checked lot of links showing same error but no solution has been provided. Anybody has any clue who already build ffmpeg on cygwin?

This is fixed in FFmpeg GIT by using av_ prefix for bswap macros. You should update to the latest git HEAD.
