I have installed MINGW64 compiler and linked it to my matlab. So on running the command "mex -setup" i get the output as:

MEX configured to use 'MinGW64 Compiler (C)' for C language compilation. Warning: The MATLAB C and Fortran API has changed to support MATLAB variables with more than 2^32-1 elements. In the near future you will be required to update your code to utilize the new API. You can find more information about this at: http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.

To choose a different language, select one from the following: mex -setup C++ mex -setup FORTRAN

Now when i try to compile the file "yprime.c" (generated using copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'),'.','f') command as given in the documentation ) using the command "mex yprime.c" i get the following erroes
