Mon Feb 19 15:30:26 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
* stdio-common/tstscanf.c (main): Add check for "0" as %d.
* sysdeps/stub/msync.c: Undo change of Jan 29; just two args.
Only some systems have three args; let them define their own stub.
* sysdeps/generic/dl-sysdep.c: Declare _dl_secure.
* sysdeps/generic/machine-gmon.h: New file.
* gmon/Makefile (distribute): Add machine-gmon.h.
* gmon/mcount.c: Undo changes of Feb 13.
Include "machine-gmon.h".
Sun Feb 18 13:24:06 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
* sysdeps/unix/sysv/linux/direct.h: File removed, since it is
identical to unix/common/direct.h.
* sysdeps/unix/Makefile [no_deps]: Don't include s-proto.d.
* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Don't add ipc.
* stdio-common/Makefile (tests): Remove scanf6.
* sysdeps/unix/sysv/linux/Makefile (non-lib.a): Append libieee.a.
* time/mktime.c (mktime): Move static variable localtime_offset to
file scope.
* stdio-common/vfscanf.c: Put '0' in buffer before scanning for %i
base indicator.
Thu Feb 15 16:56:17 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/m68k/dl-machine.h (elf_machine_load_address): Corrected.
(ELF_MACHINE_BEFORE_RTLD_RELOC): Define.
(_dl_runtime_resolve): Save %a1 as well.
(ELF_MACHINE_RUNTIME_FIXUP_ARGS): Add second dummy arg.
(elf_machine_relplt): Define.
* elf/dl-runtime.c: Include possible extra args in declaration of
