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