2.1.25 under Cygwin

[Nigel Warner]

Dear All,

        My apologies for submitting this to the development list
        but I'm not sure if I have a bug or if some feature of Lilypond
        has changed for the 2.1.25 release for Cygwin.

        Anyway, all attempts to run lilypond-book now produce the following
        error: Any ideas ?

        Regards,

        Nigel.
