locale_facets.h (num_get<>): Return advanced iterator for _M_extract_float and _M_extract_int

Browse Source 
2002-01-10  David Seymour  <seymour_dj@yahoo.com>

	* include/bits/locale_facets.h (num_get<>): Return advanced iterator
	for _M_extract_float and _M_extract_int
	* include/bits/locale_facets.tcc (num_get<>::_M_extract_float)
	(num_get<>::_M_extract_int): Likewise, all callers changed
	* testsuite/22_locale/num_get_members_char.cc: Testcase
