2004-03-31  Paolo Carlini  <pcarlini@suse.de>

	* config/locale/generic/c_locale.cc (__convert_to_v(long double&)):
	In v3 uses of sscanf, the special floating-point numbers INF,
	INFINITY, etc., cannot occur in input, therefore, if the latter
	is too large, ERANGE is always stored in errno, no need of finitel.
