Update.
1998-07-14 19:39 Ulrich Drepper <drepper@cygnus.com> * stdio-common/vfscanf.c (ungetc): Use _IO_sputbackc, not _IO_ungetc. [_USE_IN_LIBIO] (encode_error): Free cancelation handler. (conv_error): Likewise. (input_error): Likewise. (memory_error): Likewise. 1998-07-12 Mark Kettenis <kettenis@phys.uva.nl> * sysdeps/mach/hurd/dl-sysdep.c: Bring in sync with generic implementation. Include <entry.h>. Replace references to symbol _start with macro ENTRY_POINT. (__libc_uid): Remove. (__libc_multiple_libcs): New variable. (__libc_stack_end): New variable. (_dl_hwcap_mask): New variable. (_dl_important_hwcaps): New function. (_dl_show_auxv): Mark internal.
