well, for example "E" means big endian ("e" would mean little endian), so
probably this is not what you want (are you on x86?).

I guess you mean it should use the characteristics of the machine you are
running the code on by default.  Actually I thought it did nowadays (in the
bad old days it would assume sparc or something like that), but I guess I
was mistaken.  It looks like you need to say explicitly what kind of machine
you will run the code on.

Ciao, Duncan.
