One way to do this would be to write a wrapper for your command, and get

Rcmd to launch the wrapper. The wrapper can process the result code from

the real task in any way it likes.

Another would be to replace Rcmd with your own launching script; you can

see from the source code which environment variables it sets up and set 
them up yourself.

It might be safe to edit the Rcmd source (in 
src/gnuwin32/front-ends/rcmdfn.c) so that it returns the exit code from 
whatever task it launches, but that may mess up something else in the R 
build process.  Try it if you like, but I wouldn't make it a high 
priority to accept a patch that did that.
