(add_double, div_and_round_double, lshift_double, mul_double):
(neg_double, const_binop, fold): Check for signed integer overflow.
Propagate overflow flags from operands to result.
(const_binop, fold_convert): Use pedwarn for overflow warnings.
Say `constant expression', not `constant folding', for user's sake.

If we find a link pointing to ., make a similar
link to ., not a link to an absolute name.
(stdio.h): Change stdio.h to use stdarg.h to get va_list.

When link points to a dir $dirname outside $INPUT,
copy that dir into $LIB/root$dirname.  Translate the link itself
into a link to that new dir.  Make a file DONE in each treetop dir
so no treetop is scanned twice.  Improve progress messages.
