Yup. Here's a small CGI script that I wrote - nothing special - to print out the cgi environment on Windoze XP: 
#!C:\Perl\bin

use strict;

######## Start the HTML ########
print <<END_HTML;
<html>
<head>
   <title>Perl CGI Environment Variables</title>
   
<STYLE type="text/css">
<!--
H1.page_title {text-align: center; color: blue}
-->
</STYLE>
</head>

<body>

<h1 class="page_title">Perl CGI Environment Variables</h1>

<table border="1">
   <tr>
      <th bgcolor="#99ccff">\@INC Paths</th>
   </tr>
END_HTML

### 1st print out the @INC array ###
my $ct = 0;
foreach my $dir (@INC) {
   print <<END_HTML;
   <tr>
      <td><b>$dir</b></td>
   </tr>         
END_HTML
   $ct++;
}

######## Finish the @INC HTML #########
print <<END_HTML;
</table>

<br>
<br>

<table border="1">
   <tr>
      <th bgcolor="#99ccff">Env Variable Name</th>
      <th bgcolor="#99ccff">Value</th>
   </tr>
END_HTML

### Next print out all the environment variables ###
foreach my $name (sort keys %ENV) {
   print <<END_HTML;
   <tr>
      <td><b>$name</b></td>
      <td>$ENV{$name}</td>
   </tr>         
END_HTML
}

######## Finish the HTML #########
print <<END_HTML;
</table>
</body>
</html>
END_HTML

Put this in your webserver's document root. I called it "env.pl", so access it by: 
   http://your.server.com/env.pl

[download]
and see what environment variables it displays.

HTH.
