	* src/complex_io.cc : Remove ancient defines.
	* config/os/gnu-linux/bits/os_defines.h: Add defines.
	* libsupc++/tinfo2.cc: Change to cstddef.

	* include/bits/codecvt.h: Add include of c++config.h, so that
	__USE_GNU gets defined. (Important for alpha.)

	* include/c/bits/std_cwctype.h: Same.
	* include/c/bits/std_ctime.h: And here.
	* include/c/bits/std_cstdarg.h: Same.
	* include/c/bits/std_csignal.h: Same.
	* include/c/bits/std_csetjmp.h: Same.
	* include/c/bits/std_clocale.h: Same.
	* include/c/bits/std_climits.h: Touch.
	* include/c/bits/std_cfloat.h: Same.
	* include/c/bits/std_cerrno.h: Same.
	* include/c/bits/std_cwchar.h: Same.
	* include/c/bits/std_cassert.h: Same.
	* include/c/bits/std_cctype.h: Same.
	* include/c/bits/std_cstddef.h: And here.
	* include/c/bits/std_cstdlib.h: And here.
	* include/c/bits/std_cstdio.h: Same.
	* include/c/bits/std_cstring.h: Add names to namespace std::.

	* include/bits/c++config (_GNU_SOURCE): Move linux-specific macros
	from here...
	(_ISOC99_SOURCE): And this one....
	* config/os/gnu-linux/bits/os_defines.h: ...to here.

	* include/bits/codecvt.h (codecvt<_InternT, _ExternT,
	__enc_traits>::do_in): Don't cast to const, this is a bug in glibc
	prior to 2.2.
	(codecvt<_InternT, _ExternT, __enc_traits>::do_out): Same.
	* include/c/bits/std_cwchar.h: Add using declarations for mbstate_t.

2000-10-30  Steven King  <sxking@uswest.net>

	* include/bits/codecvt.h: Add cast.
	* include/c_std/stdio.h: Re-add printf using declaration.
