  I'm not sure now; I thought you said you were writing a truss tool?  Your
first email said ...

  ... but now I guess what you mean is "I downloaded and compiled a program
but didn't write any code myself".

  Yes, I know about the Detours library, I've read all about it before.

  Not to be rude, but you must be out of your mind if you think I'm going to
execute a random binary sent to me through email by a complete stranger!

  If you want Microsoft tools to support Cygwin calling sequences, you
really have to ask Microsoft to add support to their code, there's no point
asking us to somehow change the Detours library (or any other M$ tool)!

  Or you could debug the crash yourself, find out why it's happening, patch
your local copy of the detours library to work with Cygwin, and you should
have the tool you want.


    cheers,
