1.7.5: running in a non cygwin command prompt

["Shalomov, Inessa A (US SSA)" <inessa dot shalomov at baesystems dot com>]

I am trying to get the system() call working in my driver which I am running in a DOS terminal. For the sake of not porting out all of cygwin libraries and executables, I am trying to narrow down to a set of dll's and exe's required for my driver and only include those in my path. What I have gathered so far with the help of cygcheck is that I will need cyggcc_s-1.dll, cygiconv-2.dll, cygintl-8.dll, cygncurses-9.dll, cygreadline7.dll, cygwin1.dll, and sh.exe since system() executes the given command in a shell. My questions are as follows:

1) What .dll's and/or .exe's am I missing to be able to run the driver in a non cygwin command prompt? 
2) Is it possible to run my driver (see below) in a non-cygwin prompt with a reduced set of cygwin dll's and .exe's?
3) If the system() call doesn't work when used in a non-cygwin environment, is there a windows native system() equivalent call I can use?

My driver is pretty simple, just trying to get system() cmd to work in a non cygwin environment with a reduced set of dll's and exe's:

int
main(int argc, char * argv[])
{
   //Execute a popen

   int retval = system(NULL);
   if (retval == 0)
      cerr << "system returned zero; shell is not available" << endl;
   else
      cerr << "system returned non-zero value; shell is available" << endl;
   perror("The following error occurred: ");

   retval = system("HelloWorld.exe");
   if (retval == -1)
      cerr << "system call failed" << endl;
   else
      cerr << "system call successful" << endl;
   perror("The following error occurred: ");

}



Thank you,
Inessa
