Is that a 64 bit OS? We use the normal FILE * from stdlib.h. On other 64
bit OSes this gives us large files I think... Normally one can overcome
these kind of problems by using the operating system dependent types for
off_t (offset ptr.)

By the way was that a trr file or a xtc file? That could also make a
difference.

Groeten, David.
