C++ Code written in VS2010 is working in Linux but not in windows

Hi

I am working on VS2010 mixed-programing and use the Intel Compiler / VisualStudio (Intel Parallel 2015) to compile my project in VS 2010.

#include <conio.h>
#include <string.h>

//#define readfile readfile_

extern void readfile(char*, int*);

int main()
{
    int n, count;
    char Fname[9];
    char Name[10];

    strcpy(Fname,"AMIN.for");
    fprintf( stderr, "%s\n", Fname);

    readfile( Fname, &n , strlen (Fname));
    fprintf( stderr, "n = %d\n", n);
//  fprintf( stderr, "%s\n", Name);
    getch();
    return 0;
}
subroutine - Lib fortran:

      subroutine readfile( fname1, m )
      character fname1*(*)
      integer m
      integer iounit,i
      iounit=15
      write(*,*) fname1
c10   format (a9)
      open(iounit,file = fname1,action='read')
      read (iounit,*) m
c20    format (i10)
      write(*,*) m
      close(iounit)
      return
      end subroutine

My program is compiling on Linux but not compiling in windows(VS) I don't know what happen exactly. Thanks
