descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.
the first two items result in the addition of code similar to the
following in various functions:
_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif
space in the input stream since there may be `conversion' specifiers following
the (format string) white space that do not operate on the input stream,
i.e. %n; from Chris Torek.
Like Plauger's implementation in "The Standard C Library", we use strtod(),
which will limit the range of values that can be converter properly if
long double has greater precision or range than double.
We will need a string to long double function to handle this properly, but
this change is better than the previous behavior of ignoring the existance
of long doubles.
