1997-04-09 01:24 Ulrich Drepper <drepper@cygnus.com> * rellns-sh: Rewrite to work also in presence of symlinks. * arpg/argp-fmtstream.c: Add casts to prevent warnings. * argp/argp-fmtstream.h: Likewise. * argp/argp-help.c: Likewise. * elf/dl-minimal.c: Add definition of calloc. * elf/version.c: Add casts to prevent warnings. (_dl_check_map_versions): Use calloc instead of malloc+memset. * locale/setlocale.c (_nl_current): Add element with index LC_ALL. Reported by Greg McGary <gkm@eng.ascend.com>. * manual/libc.texinfo: Update malloc documentation for new malloc. * manual/memory.texi: Likewise. Patch by Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>. * math/libm-test.c (check_long): New function. (check_longlong): New function. (rinttol_test): New function. (rinttoll_test): New function. * nis/nss_compat/compat-grp.c (in_blacklist): Improve a bit. * nis/nss_compat/compat-pwd.c: Likewise. * nis/nss_compat/compat-spwd.c: Likewise. * stdlib/erand48_r.c (erand48_r): Build double value using ieee754_double union and use random bits in different order to increase effect of seed. Reported by David Mosberger-Tang <davidm@AZStarNet.com>. * sunrpc/svc_auth.c: Moved to ... * sysdeps/generic/svc_auth.c: ...here. * time/time.h: Pretty print. 1997-04-08 07:19 H.J. Lu <hjl@gnu.ai.mit.edu> * libio/genops.c (_IO_flush_all_linebuffered): don't flush on a read-only stream. 1997-04-09 01:19 Ulrich Drepper <drepper@cygnus.com> * malloc/malloc.c (mALLOC_STATs) [MALLOC_DEBUG>1]: Put declaration in correct place. Patch by Marcus G. Daniels <marcus@cathcart.sysc.pdx.edu>. 1997-04-07 15:34 Ulrich Drepper <drepper@cygnus.com> * stdio-common/Makefile (tests): Add tst-ferror. * stdio-common/tst-ferror.c: New file. Some tests for error indicator of streams. * stdio-common/tst-ferror.input: New file. * isomac.c: Let tests not fail because the compiler defines itself symbols which violate the name space rules. gcc defines symbols for the architecture which are not protected by an underscore character. * math/Makefile (libm-support): Add s_rinttol and s_rinttoll. (libm-calls): Add s_clog. * sysdeps/libm-ieee754/s_clog.c: New file. Implementation of logarithm of complex value. * sysdeps/libm-ieee754/s_clogf.c: New file. * sysdeps/libm-ieee754/s_clogl.c: New file. * math/libm-test.c (clog_test): Compile this function. Fix a few typos. (main): Call clog_test. * sysdeps/libm-ieee754/s_rinttol.c: New file. Round long double value to long int. * sysdeps/libm-i387/s_rinttol.S: New file. * sysdeps/libm-ieee754/s_rinttoll.c: new file. Round long double value to long long int. * sysdeps/libm-i387/s_rinttoll.S: New file. * sysdeps/libm-ieee754/s_rintl.c: Many corrections. The previous version was full of errors. * math/math.h (rinttol): Argument is of type `long double' not `double'. (rinttoll): Likewise. (roundtol): Likewise. (roundtoll): Likewise. 1997-04-06 11:32 H.J. Lu <hjl@gnu.ai.mit.edu> * posix/getopt.c (_getopt_initialize): Preserve optind. (_getopt_internal): Set optind to 1 if optind == 0 before calling _getopt_initialize (). 1997-04-05 16:45 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/rpcsvc/nislib.h: Change const nis_name to new type const_nis_name. * nis/nis_intern.c: Likewise. * nis/nis_intern.h: Likewise. * nis/nis_server.c: Likewise. * nis/nis_subr.c: Likewise. * nis/nis_table.c: Likewise. * nis/nis_names.c: Likewise. Fill out ns_request structure in nis_add(). * nis/nss_compat/compat-pwd.c: Use reentrant netgroup functions. * nis/nss_compat/compat-spwd.c: Likewise. 1997-03-27 07:37 H.J. Lu <hjl@gnu.ai.mit.edu> * libio/fileops.c (_IO_file_overflow): Set error when try to write on a read-only stream. * sysdeps/gnu/utmpbits.h (ut_xtime): New symbol. (ut_time): Define it only if _NO_UT_TIME is not defined. 1997-04-06 00:42 Ulrich Drepper <drepper@cygnus.com> * misc/tst-tsearch.c: Include <string.h>. Define _GNU_SOURCE only if not already defined. 1997-04-05 16:14 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/netatalk/at.h: Include <sys/socket.h> to get definition of sa_family_t for <linux/atalk.h>. Reported by a sun <asun@zoology.washington.edu>. * malloc/malloc.c (cALLOc): Little optimization.
