*** empty log message ***
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 fixup.
