This is at least not recommended and certainly highly discouraged.  Cygwin's
use of the registry is an implementation detail and could (read as "will")
change at any moment.  But, since you're doing a non-standard installation,
you must have accepted that you're "living on the edge".  Problems resulting
from that are, of course, your own.

1.5.x apps use 64-bit I/O by default.  That's the major change.

No, there will be no non-9x/Me calls made for 9x/Me.

You may need a debugging environment, though you could try strace and 
look to see if its output helps you.
