Tom,

I know Cygwin supports Win32 paths.  I suspect the issue here is mount
type (text vs. binary).  If you use a POSIX path, you can control whether
your files are opened in text or binary mode.  To tell the truth, I don't
know exactly what the mode defaults to if a Win32 path is used (and yes, I
could look at the source, but I'm too lazy).  It may well be (and this is
a WAG) that it defaults to text mode, and the '\r' at the end of the "#!"
line is considered part of the shell (thus causing exec to fail).
	Igor
