it seems that  xvidcore-1.0.0-rc4\build\generic\libxvidcore.def only exports
9 functions,such as:
EXPORTS
 xvid_global; 
 xvid_decore; 
 xvid_encore; 
 xvid_plugin_single;
 xvid_plugin_2pass1;
 xvid_plugin_2pass2;
 xvid_plugin_lumimasking; 
 xvid_plugin_dump; 
 xvid_plugin_psnr; 
so other functions like: idct,fdct are unresolved external symbols.

so i try to modify the libxvidcore.def to extern more functions, no more link errors now.
But when run xvid_bench.exe,runtime error happened.  Because functions link emms,idct,fdct... 
are dynamically decided, make a static lib seems not a good idea. So i move the xvid_bench.c to the
xvidecore project and change the entry main() to xvid_bench(), export it in libxivdcore.def. In my 
test_bench function, call xvid_bench(argc,argv) directly.
It works now. But certianly this is not a good method, maybe someone else can do it in a more reasonable way.
