Prevent strange crashes in fmt with absurd goal lengths introduced by the

2007-10-17T11:41:40+00:00

support for wide characters.

If the sizeof (wchar_t) times max_length would yield a value beyond
representation in a size_t, exit with a usage error up front, rather than
strange errors down the line from trying to malloc (well, realloc) with a size
of 0.

This is perhaps not the optimal behaviour - a clamp may be more appropriate as
we clamp the value of max_length now anyway, but this is at least better than
segfaulting or worse.  On systems which are friendly to malloc with a value of 0
the results could end up being strange corruption of the output.

Remove unnecessary SRCS= where could be guessed directly by our
