See https://svn.r-project.org/R/trunk/src/gnuwin32/front-ends/rcmdfn.c. 
  The exit code should be the return value from the rcmdfn() function. 
The return value 1 looks ambiguous; other values other than 0 appear to 
correspond to error messages that should have been printed.  0 means 
everything was fine.
