I don't understand why you wouldn't just use samp.sh unchanged from
Unix without changing it to a .bat file and use either product the way
it was designed without SFU with cygwin binaries or vice versa.

But, unless this is just a simple PATH environment variable problem, i'm
sorry, but we're really not going to be helping you debug problems with
a combination of both Cygwin and SFU.  They are competing products and
there really is no reason to use them in conjunction with each other.
