perl 5.004_02 for Win32 binary distribution from CPAN
>Description:
The shebang syntax #! is interpreted by Apache; the standard file association
is ignored (*.pl => c:/perl/bin/perl.exe "*.pl").

Win32 uses file associations in the registry to determine how to make 
non-executable files executable (.bat, .cmd, .pl, .tk, .py, etc.).
>How-To-Repeat:
Configure any CGI directory that has a perl script 
with a unix style #!/usr/bin/perl as the first line.
>Fix:
Apache will look for a file called /usr/bin/perl (on the default drive,
the same as Apache is installed on).  If the perl interpreter is found
there (simply by copying c:/perl/bin/perl.exe to c:/usr/bin/perl) then
Apache will load the perl interpreter and run the CGI script.

This way, CGI scripts can remain mostly unmodified between NT and Unix
hosts (CR/LF transformation may still be needed).

Note that with the 5.004_02 binary distribution, simply copying and renaming the
(8K) interpreter executable from the installed directory into c:/usr/bin
is sufficient.  The perl interpreter will find the standard installation
directory and load the required DLLs and perl library files.

The fact that NT does not see an extensionless c:/usr/bin/perl as an 
executable file does not matter
