Understood. I'll try rephrase my original question in terms of ssh.

Hmm. I tried to replicate this with 'ssh' as well, after you mentioned
it. Here's what I did:
1. Use Putty to connect to the cygwin machine via SSH.
2. Use 'ssh-keygen' to create a key on the cygwin machine, and add it
to the authorized_keys file.
3. Use 'ssh-agent' and 'ssh-add' to hold my key in memory so it can be
used without a prompt
4. Use 'ssh localhost <command>' to simulate the 'plink' setup I
described earlier
What I found is this:
(a) ssh localhost echo $PATH
returned the correct cygwin path, but
(b) ssh localhost 'echo $PATH'
returned the full Windows path, not the cygwin path, and
(c) ssh localhost "echo $PATH"
returned the correct cygwin path as well. But as I think about it, I
actually can't change the quotes used around the command (since it's
issued by a program over which I have no control). What I CAN
manipulate is the cygwin environment contacted by the ssh/plink program.

Let me rephrase this a bit. What happens differently between (a) and
(b) above on the _server_ side?

Can I change the cygwin environment (server side) to handle both (a) and
(b) in the same way? I'm familiar with Linux, but Cygwin (and
especially its interaction with Windows: environment, permissions, etc)
is brand new to me.
The quotation difference is step in the right direction (I know what to
rule out), and I'm sure with a bit more info I'll be able solve my
problem. I appreciate your help.
Thanks,
Tim
