Your shell script is incorrect, and I don't see how it worked under
1.5. This line:

>        set EXPLOR='/cygdrive/c/windows/explorer.exe'

does NOT set a variable named EXPLOR.  Instead, it sets the first
positional argument ($1) to the string
"EXPLOR=/cygdrive/c/windows/explorer.exe".  Whatever the old value of
$1 was, it's now gone.

To fix, get rid of the "set".  In sh and derivatives, "set" sets the
positional arguments (and optionally flags that affect the shell's
behavior); it does NOT set variables.  Just use the assignment syntax
(var=value) by itself for that.
