Subject: [PATCH] Update.

2002-12-31  Ulrich Drepper  <drepper@redhat.com>

	* string/string-inlines.c: Define __memcpy_g and __strchr_g macros
	to avoid using the exported symbols.  Define aliases with the
	original names separately.

	* include/time.h: Add libc_hidden_proto for __strftime_l.
	* include/wchar.h: Add libc_hidden_proto for __wcsftime_l.
	* time/strftime.c: Always use libc_hidden_def if _LIBC.

	* libio/libioP.h: Add libc_hidden_proto for _IO_file_open.
	* libio/fileops.c: Add libc_hidden_def for _IO_file_open.

	* malloc/mtrace.c: Add libc_hidden_proto and libc_hidden_def for
	tr_break.

	* csu/Makefile (routines): Add dso_handle.
	* csu/dso_handle.c: New file.
