Woops. That's wrong already. $PROG_ENV should have been expanded in
"export PATH=" command, so "echo $PATH" should not show "$PROG_ENV/.." but
"/cygdrive/c/prog/bin/nt....", as below:

What shell are you using?
cheers,

I do not quite get what you are saying and your example, I am using BASH
which the default cygwin shell.
In your example you can see that "/cygdrive/c/prog/bin/nt" is the first
element in $PATH, that is what we want; "$PROG_ENV/bin/nt/prog.exe" is
expanded to "/cygdrive/c/prog/bin/nt/prog.exe" correctly.
These are all as expected, the problem is why the correct path can not be
taken.
Do I miss anything?
