Log message:
	2003-12-03  Paolo Carlini  <pcarlini@suse.de>
	
	PR libstdc++/12791
	* include/bits/locale_facets.tcc (time_get::_M_extract_num):
	Rewrite, stop the parsing as soon as a digit cannot possibly
	lead to a final number within the bounds; otherwise, simplify,
	avoiding __ctype.is() and atoi().
	* testsuite/22_locale/time_get/get_date/char/12791.cc: New.
	* testsuite/22_locale/time_get/get_date/wchar_t/12791.cc: New.
	
	* include/bits/locale_facets.tcc (time_get::_M_extract_via_format):
	Minor tweak: a 4-digit integer cannot be bigger than 9999.
	
	* testsuite/22_locale/time_get/get_date/wchar_t/1.cc: Use
	type-correct wchar_t string literals.
	* testsuite/22_locale/time_get/get_monthname/wchar_t/1.cc: Ditto.
	* testsuite/22_locale/time_get/get_time/wchar_t/1.cc: Ditto.
	* testsuite/22_locale/time_get/get_weekday/wchar_t/1.cc: Ditto.
	* testsuite/22_locale/time_get/get_year/wchar_t/1.cc: Ditto.
