[Patch] Fix libstdc++/12750


Hi,

the below (which cleanly applies on top a slightly modified version
of the posted _M_extract_float/int patch) enables the _M_extract_format
switch to deal with formatting code 'e'.

Tested x86-linux, will commit soon together with the previous one...

Paolo.

2003-10-27  Paolo Carlini  <pcarlini@suse.de>

	PR libstdc++/12750
	* include/bits/locale_facets.tcc
	(time_get::_M_extract_via_format): Deal with code 'e'.
	* testsuite/22_locale/time_get/get_date/char/4.cc: New.
	* testsuite/22_locale/time_get/get_date/wchar_t/4.cc: Ditto.

	* include/bits/locale_facets.tcc
	(time_get::_M_extract_via_format): Tweak to absolutely avoid
	dereferencing the end iterator.
