Ah, no, what I'd like to know is not the lisp return value, but the
string inserted in the buffer.  What string is inserted in the buffer
when you put the point just after the following form in *scratch* buffer
and type C-x C-e ?

(call-process "kpsewhich" nil
                               (list standard-output nil) nil
                               "--expand-path" "{.,..}")

I suspect that it is ".:..", not ".;..".  If this speculation is
correct, then cygwin version of kpsewhich is used at auto detection.

Hmm.
