Consult the section on '-s' at http://perldoc.perl.org/perlrun.html:
-s
enables rudimentary switch parsing for switches on the command line
after the program name but before any filename arguments (or before
an argument of --). Any switch found there is removed from @ARGV and
sets the corresponding variable in the Perl program. The following
program prints "1" if the program is invoked with a -xyz switch, and
"abc" if it is invoked with -xyz=abc.
#!/usr/bin/perl -s
if ($xyz) { print "$xyz\n" }
Do note that a switch like --help creates the variable ${-help} ,
which is not compliant with use strict "refs" . Also, when using
this option on a script with warnings enabled you may get a lot of
spurious "used only once" warnings.
So this is probably what you want:
perl -MParse::RecDescent -s -RD_AUTOSTUB - grammar NewMakepp::Grammar
Untested, you may need to move -s, '-RD_AUTOSTUB and the '- grammar
...' arguments around to make it work.

I use perl -MParse::RecDescent - grammar NewMakepp::Grammar to create a parser
module.
What do I do in order to generate stubs for undefined rules?
How do I pass RD_AUTOSTUB?
