[FFmpeg-user] avcodec-53.dll invalid or corrupt

I am brand new to using ffmpeg. I am trying to build ffmpeg libraries using mingw/msys as I am trying to use those libraries in my vc++ 2008 project. I followed the instruction listed in the ffmpeg documentation http://www.ffmpeg.org/general.html#Using-static-libraries
To build shared libraries. When I try to use in my vc++ project., first it said, it could not locate avcodec-53.dll. Then I mentioned this dll under project properties->linker->input->additional dependencies. Now it says 'avocodec-53.dll is invalid or corrupt'. Can you please help me out in this? I am not much familiar with linux. I used 'output-example.c' for my vc++ win32 console project.
Also I don't know how to use this line mentioned in the document,

extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];

I also created  'import libraries that work with the /OPT:REF option' as mentioned in the document.

One thing  I noticed was, when I issued ' ./configure -enable shared -disable-yasm'  command, msys executed but with a warning saying, 'pkg-config not found, library detection may fail.'

Thanks in advance
