error: implicit declaration of function 'strtok_r' [-Werror=implicit-function-declaration]

[Kyle]

I'm having troubles compiling FFmpeg for Windows. This error comes up:

/home/kyle/software/ffmpeg/source/ffmpeg-git/libavfilter/asrc_abuffer.c: In function 'init':
/home/kyle/software/ffmpeg/source/ffmpeg-git/libavfilter/asrc_abuffer.c:259:5: error: implicit declaration of function 'strtok_r' [-Werror=implicit-function-declaration]

Here is what V=1 shows:

Here is my configure:

cross_prefix=i686-w64-mingw32- target_os=mingw32 arch=x86 pkg_config=pkg-config ../source/ffmpeg-git/configure --enable-gpl --enable-version3 --enable-runtime-cpudetect

I've giving this critical priority because FFmpeg is unable to be built with MinGW-w64.

I'm using the latest FFmpeg.

Should be fixed.

Did you report to the mingw64 developers that strtok_r (or its definition?) is missing?
I believe it is defined in Posix.
