That's your problem, right there: using `fscanf' for free-format input
is a Bad Idea (tm).  Use `fgets', and then process the string
yourself, either with `sscanf' or with `strtol'.  The latter is
generally easier, since it returns a pointer to the unprocessed part
of the string, which makes it easier to see what character confused
it.
