1997-06-14 00:39 Ulrich Drepper <drepper@cygnus.com> * libc.map: Add more libio functions which are used in libio.h. * login/Makefile (libutil-routines): Move updwtmp to ... (routines): ...here. Suggested by Mark Kettenis <kettenis@phys.uva.nl>. * sysdeps/stub/s_erfl.c: Add stub definition of erfcl. Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>. 1997-06-13 21:10 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nis_add.c (nis_add): Create object name only if not set. * nis/nis_clone.c: Use calloc instead of malloc to prevent RPC encode errors. * nis/nis_modify.c (nis_modify): Create default object entrys if given are NULL. * nis/nis/nis_table.c (nis_add_entry, nis_modify_entry): Likewise. 1997-06-13 14:17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/i386/addmul_1.S: Replace size with sizeP, otherwise the define might also replace the expanded macro ASM_SIZE_DIRECTIVE. * sysdeps/i386/submul_1.S: Likewise. 1997-06-13 12:19 Ulrich Drepper <drepper@cygnus.com> * elf/rtld.c: Print version information if LD_TRACE_LOADED_OBJECT and LD_VERBOSE are given. * elf/ldd.sh.in: Add -v|--verbose option.
