In the upcoming Standard C++ Library (see: P.J. Plauger, 
"The Draft Standard C++ Library", Prentice Hall, ISBN 0-13-117003-1)
six constants are defined for 'openmode':

   app, ate, binary, in, out, trunc (p.113 Plauger)

It seems practical to stick as close to this upcoming standard as possible.
But I guess this discussion is more gcc-related than DJGPP-related.
