	functionality.
	* locale/langinfo.h: Define symbols only for currently implemented
	functionality.
	* locale/categories.def: Define elements for currently implemented
	functionality.
	* locale/C-collate.c: Comment out definitions of arrays with symbol
	name definitions etc.
	(_nl_C_LC_COLLATE): Update for currently defined information.

	* intl/libintl.h: Remove dcgettext macro definition.
	* intl/gettextP.h: Declare _nl_msg_cat_cntr.

	* locale/iso-4217.def: Add NAD.  Remove a few obsolete entries.

	* sysdeps/sparc/fpu/ftestexcept.c (fetestexcept): Use proper type
	for __fenv_stfsr argument.
	* sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list: Add
	truncate64, ftruncate64, fstat64, lstat64, stat64 and mmap2.
	Remove ugetrlimit.
	* sysdeps/unix/sysv/linux/sparc/sparc32/mmap64.c: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/kernel_stat.h
	(XSTAT_IS_XSTAT64): Define.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Add
	__libc_lseek64, __libc_pread, __libc_pread64, __libc_pwrite
	and __libc_pwrite64.
	Remove oldgetrlimit and oldsetrlimit.
	* sysdeps/unix/sysv/linux/sparc/sparc64/fxstat64.c: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/lxstat64.c: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/xstat64.c: New file.

	* sysdeps/unix/sysv/linux/fxstat64.c (__fxstat64): Pass the buf
	pointer to the syscall, not address of that pointer.
	* sysdeps/unix/sysv/linux/lxstat64.c (__lxstat64): Likewise.
	* sysdeps/unix/sysv/linux/xstat64.c (__xstat64): Likewise.
	(__syscall_stat64): Provide proper prototype.

	* sysdeps/unix/sysv/linux/ftruncate64.c (ftruncate64): Share
	has_no_truncate64 between truncate64 and ftruncate64.
	* sysdeps/unix/sysv/linux/truncate64.c (truncate64): Likewise.

	* sysdeps/unix/sysv/linux/kernel-features.h
	(__ASSUME_TRUNCATE64_SYSCALL, __ASSUME_MMAP2_SYSCALL,
	__ASSUME_STAT64_SYSCALL): Define on Sparc for kernels >= 2.3.35.

1999-12-22  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add __libc_lseek64,
	__libc_pread, __libc_pread64, __libc_pwrite and __libc_pwrite64.
