Greetings your worthiness(es):

I am trying to use the C::Scan module to extract function names, argument lists, and macros from C source file, but am having difficulty making it work. I am using the source supplied in the module review on perlmonks (here!) and it fails when I try to extract the fdecls -- it reports:
'cppstdin' is not recognized as an internal or external command, operable program or batch file."

I found a post burried here that reported the same problem, but there was no solution provided. I must assume that I have done something wrong, but don't know what.

The C code to be parsed was extremely trivial (and omitted).

Any help would be greatly appreciated. Of course, if there is a better way, I would like to know that as well.
My perl isn't good enough (yet) to know how to fix this --

You may contact me directly at: raz@poetworld.net Thanks you (all) very much! 

use C::Scan;

$c = new C::Scan(filename => 'test.c',
                filename_filter => 'test.c'
               );

#
# Fetch and iterate through information about function declarations.
#
my $array_ref = $c->get('fdecls');
foreach my $func (@$array_ref) {
   my ($type, $name, $args, $full_text, undef) = @$func;
   foreach my $arg (@$args) {
       my ($atype, $aname, $aargs, $full_text, $array_modifiers) = @$a
+rg;
   }
}

#
# Fetch and iterate through information about #define macros w/args.
#
my $hash_ref = $c->get('defines_args');
foreach my $macro_name (keys %$hash_ref) {
    print "$macro_name \n";
   my $array_ref = $macros_hash{$macro_name};
   my ($arg_ref, $macro_text) = @$array_ref;
   my @macro_args = @$arg_ref;
}
