The problem is that I have not the faintest insight into .Net.  This is
an application written in a language I don't know, using a class library
I don't know, using a compiler I don't know.  And the executable isn't
even a Cygwin application so it doesn't call Cygwin functions.  So I
have no idea what problem this application has.  What on earth is it
trying to tell me?
