If the selected target is \fIvvp\fP, the \fB\-v\fP switch is appended
to the shebang line in the compiler output file, so directly executing
the compiler output file will turn on verbose messages in \fIvvp\fP.
This extra verbosity can be avoided by using the \fIvvp\fP command to
indirectly execute the compiler output file.
