In that case, the application gets the command line via GetCommandLine,
which in turn is converted to argc,argv by the Cygwin DLL ebfore calling
main.

Or 

  #ifdef __CYGWIN__
  int main (int argc, char** argv)
  #else
  int realmain (int argc, char** argv)
  #endif

Can you quickly check if that works?  If so, we have a bit less pressure
to fix libcmain.

Yes, I saw that while debugging.
