[FFmpeg-user] compile ffmpeg in windows 8.1 problems

[BC@︻$▆▇◤]

the mingw msys cmd returns:
  
 $ ./configure --enable-shared --disable-static --enable-memalign-hack

 gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.
 If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
  
 i compiles in windows have to make it  cross-compiler?
  
 my mingw path:
 C:\MinGW
 C:\MinGW\msys\1.0
