Trying to match window's path

[Gu, Han]

Hi,
Still very noob when it comes to perl. Just have a quick question. I am trying 
to match a string that is window's path

Sample,

$s1 = "c:\\log\s1.log";

$s2 = $s1;

If ($s1 =~ m/$s2/i) {
            print "matched\n";
}

It just wouldn't match. I can put the actual string into m//i, which would 
work, but I have to make it work with variable, since I'll be reading in the 
actual string from a file.

Greatly appreciate any answer I get.

Thx

Han
