1998-10-25  Ulrich Drepper  <drepper@cygnus.com>

	* include/features.h: Define __USE_POSIS199506 is _POSIX_C_SOURCE is
	greater or equal than 199506L.

	* sysdeps/generic/bits/types.h (__fd_set): Define element as fds_bits
	only is __USE_XOPEN.  Otherwise use __fds_bits.
	* sysdeps/unix/sysv/linux/alpha/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/types.h: Likewise.
	* sysdeps/unix/sysv/sysv4/solaris2/bits/types.h: Likewise.

1998-10-24  H.J. Lu  <hjl@gnu.org>

	* locale/programs/charmap.c (parse_charmap): Accept tok_string
	for <code_set_name>.

	* string/bits/string2.h: Inline strdup+friends only if
	__USE_MISC || __USE_GNU (prevents namespace pollution).
