[Ffmpeg-devel] [PATCH] Fix for non-GNU sed.

[demo-n]

Hi

"--disable-decoder=NAME" option of ./configure doesn't work with
non-GNU sed programs.
Takashi Mochizuki aka MyCometG3 known as an author of mp4vEncoder
pointed out it.
He concluded that as a result of the investigation, there was a
problem in the following function in ./configure script.

filter_out(){
    pattern="$1"
    shift
    echo "$@" | sed "s%\\<$pattern\\>%%g"
}

According to the info page, \< and \> are a GNU extension.
Because Mac OS X uses non-GNU sed, this function doesn't work correctly.
Therefore, I made the attached patch.
This patch removes the GNU sed dependency on ./configure.
filter_out() with it can disregard "oggvorbis_encoder" when the
$pattern is "vorbis_encoder".
