This is not very robust, but should be along the lines of what you are doing.

Code:
#!/usr/bin/perl -w

use v5.8.0;

my $test = <<EOF;
-- This is comment
A
/* Hello
   This should be ignored
   and also this line */
B
C
D
EOF

my $linecount = 0;
my $ignoreLine = 0;
open(FILE, '<', \$test);
while ($line = <FILE>) {
	$linecount++;
	next if ($line =~ /^--/);
	if ($line =~ /^\/\*/) {
		$ignoreLine = 1;
		next;
	} elsif ($line =~ /\*\//) {
		$ignoreLine = 0;
		next;
	}
	next if ($ignoreLine);
	print $line;
}
close(FILE);

print "Lines = $linecount\n";

setusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
