Ooops!

You are absolutely right. So how can I update my code above, except from stating here:

Update (thanks to antirice): 

my $qs =qr/'(?:[^\\']|\\.)*'/;
my $qqs=qr/"(?:[^\\"]|\\.)*"/;

The complete code (I also added some enhancements/bug-fixes after testing with my colleague)... 
#!perl
use strict;

my $qs =qr/'(?:[^\\']|\\.)*'/;
my $qqs=qr/"(?:[^\\"]|\\.)*"/;
my $ncs=qr<(?:[^'"/]|/[^/*])>; #'
my $nocomment=qr/(?:$ncs|$qqs|$qs)*/;

my $hit;

while (<>) {
        s/[\r\n]//g;
        # remove multiline /* comment
        if ($hit= s{^($nocomment)/\*(?:[^*]|\*[^/])*$}{$1}o ... s{^.*?
+\*/}{}) {
                redo if $hit=~ /E0/i;
                $_='' if $hit>1;
                print $_,"\n";
                next;
        }
        # remove one-line /*...*/ comment
        redo if s{^($nocomment)/\*.*?\*/}{$1}o;
        # remove // comment
        s{^($nocomment)//.*}{$1}o;
        print $_,"\n";
}
