When the code was written, in the vc6 days, the vcvars script spit out 
output always. This obviously is rather annoying when one is really 
interested compile output. But we do check for the status result of the 
command, that's what the "&&" is there for. It short circuits the 
running of the command so that it fails as soon as vcvars fails.
