	Abstract out the underlying "C" io bits.
	* bits/std_new.h: Remove <stl_config> include, as well as <cstddef>.
	* stl/bits/stl_string_fwd.h: Remove <stddef> include.
	* bits/std_cwchar.h: Wrap with _GLIBCPP_USE_WCHAR_T guards. Don't
	include <cstddef>.
	* stl/bits/stl_config.h: Don't include _G_config.h.
	
	* bits/basic_file.h: Allow for non-inheritance based __basic_files.
	* config/c_io_libio.h (_GLIBCPP_BASIC_FILE_INHERITANCE): Define.
	* config/c_io_libio.cc: Tweak.
	
	* src/Makefile.am (TOPLEVEL_INCLUDES): Add includedir.
	* src/Makefile.in: Regenerate.
	* Makefile.am (AM_MAKEFLAGS): Define includedir so that
	prefix/include files will be picked up.
	* Makefile.in: Regenerate.
	* math/Makefile.am (TOPLEVEL_INCLUDES): And here.
	* libio/Makefile.am (TOPLEVEL_INCLUDES): And here.
	
	* bits/std_ios.h: Include <bits/c++io.h> instead of libio.
	* bits/fpos.h: And here.
	* bits/basic_file.h (get_fileno): Move definition from ...
	* src/basic_file.cc (std): To here.
	* bits/fpos.h: Move types for streamoff, streampos to..
	* bits/basic_file.h: Move __c_file_type and fpos typedefs to...
	* config/c_io_libio.h: ...here.
	(_GLIBCPP_[BOOLALPHA, HEX, DEC, FIXED, INTERNAL, LEFT, OCT, RIGHT,
	SCIENTIFIC, SHOWBASE, SHOWPOINT, SHOWPOS, SKIPWS, UNITBUF,
	UPPERCASE, ADJUSTFIELD, BASEFIELD, FLOATFIELD, BADBIT, EOFBIT,
	FAILBIT, GOODBIT, APP, ATE, BINARY, IN, OUT, TRUNC): New macros to
	abstract out bits in ios_base.
	* bits/ios_base.h: Re-macrofy.
	* src/basic_file.cc : Rename, move to
	* config/c_io_libio.cc: Here.
	* config/c_io_libio.h: New file. Include libio.
	* bits/c++config.h: Don't define _GLIBCPP_USE_LIBIO.
	* configure.in (blddir): Add enabling bits for GLIBCPP_ENABLE_CSTDIO.
	* configure: Regenerate.
	* src/Makefile.am (sources): Take out basic_file.cc and add c++io.cc.
	(generated_headers): Add c++io.h
	* acinclude.m4 (GLIBCPP_ENABLE_CSTDIO): New function to select
	underlying "C" io library.
	* acinclude.m4 (GLIBCPP_CHECK_LIBIO): Roll functionality into
	GLIBCPP_ENABLE_CSTDIO.
	
	* configure.in: Add configure bits for cross compiling non-newlib
	targets. .
	GLIBCPP_CHECK_COMPILER_VERSION: Take out this test for this
	target, as we assume g++ support is not the limiting factor.
	GLIBCPP_CHECK_LIBIO: Same, know we don't need libio.
	* configure: Regenerate.
