GCC provides for such a command. The stand-alone build of pidl is
mostly used for generating ethereal dissectors at the moment, which is
done on Linux - the portability requirements aren't very high here,
nor will regular users have to run pidl. Also, the alternative would
be adding a configure stage to pidl (we currently don't have any), and
I'm very hesitant to do that for just 'cpp'.
