I've been playing around with this, too. I have a Windows 'native' version of
Perl 5.8.0 available to play with and when I used it, I got the same error as
Andrew did.
I'm not sure how you did your cmd.exe test? I tried it, in the form of a
shebang file. It 'worked' but it did complain about the shebank line not being
recognized. But that's a side issue, just curious;-)
What I think is going on here has to do with how the "exec" for shebang does its
thing. The interpreter named in the shebang line is exec'd, with the path name
of the script file as an argument. I'd suggest that the Windows/DOS commands in
question (my perl 5.8.0 and CQPerl) are unable to find the file, in the failing
case, because they are reading a symlink, which they don't know how to deal
with. So they are reading the content of the symlink, not what it points to.
I'm not sure why cmd.exe isn't having the same problem. Perhaps there's
something in Windows/DOS program linking that needs to be done to get them to
work with .lnk files? Like the business of linking into a program the ability
to do wild card expansion.
