Paul,

I was able to reproduce your output on Cygwin 1.3.20.  The invokation
method (i.e. POSIX vs. mixed path) did not matter, though the DOS line
endings did.

Try invoking your script as

C:/cygtest/testscript 2>&1 | od -c

and look at the result - it should be very informative.  I got:

$ c:/cygwin/tmp/kshtest/testscript 2>&1 | od -c
0000000   c   :   /   c   y   g   w   i   n   /   t   m   p   /   k   s
0000020   h   t   e   s   t   /   t   e   s   t   s   c   r   i   p   t
0000040   [   2   ]   :       s   e   t   :       -  \r   :       u   n
0000060   k   n   o   w   n       o   p   t   i   o   n  \n
0000075

Also, what does your mount table look like?  Do you, by any chance, have a
text-type mount for /cygdrive?  I'm assuming your pdksh is self-built.
Did you link with automode.o?
