Error messages go to one of two places. Errors from the compiler
default to stderr but can be redirected with the -E option (-Efoo would
sent them to a file named "foo"). Other errors (problem communicating
with the RCX, illegal command line, etc) go to stdout under Windows and
stderr on other platforms.
If there's a consensus that stderr is always a bad choice under Windows,
I'll change the compiler to default to stdout for its error messages
under Windows (but still redirectable with the -E option).

actually it needs to do:
return RCX_ERROR(result) ? result : 0;
because positive numbers are valid return codes for certain operations,
but would potentially confuse calling programs that expected 0 to mean
success. I changed the source already, I'm not sure when it will get
released.
