> 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:

My suggestion:

    * Drop the dependency on sh.exe by using one of the exec() calls
      rather than system().
    * Apply static linking: gcc -static -static-libgcc ..., so you'll
      only need cygwin1.dll
