Makefile.am (exception): Change exception.cc to exception_support.cc.

2000-10-18   Benjamin Kosnik  <bkoz@purist.soma.redhat.com>

	* libsupc++/Makefile.am (exception): Change exception.cc to
	exception_support.cc.
	(CXXLINK): Remove bogus --tag CC.
	* libsupc++/Makefile.in: Regenerate.
	* libsupc++/exception.cc: Move to...
	* libsupc++/exception_support.cc: ...here.

	* src/Makefile.am: Remove bogus --tag CC.
	* src/Makefile.in: Regenerate.

	* include/bits/locale_facets.tcc (use_facet): Simplify.
	* include/bits/locale_facets.h (use_facet<ctype<char> >): Correct
	use_facet declaration. Replace 'const ctype<T>' with ctype<T>.
	(use_facet<ctype<wchar_t> >): Same.
	* src/locale-inst.cc: Remove explicit instantiation.
	* src/locale.cc: Correct signature here too.
	(_Bad_use_facet::what()): Correct error string.
	* include/bits/localefwd.h: Correct comment.

	* mkcheck.in (C_DIR): Change libsupc++/include to libsupc++.
