1998-09-09 09:32 Ulrich Drepper <drepper@cygnus.com> * sysdeps/powerpc/dl-machine.h (elf_machine_rela): Make function inline. 1998-09-07 Paul Eggert <eggert@twinsun.com> * time/mktime.c (__EXTENSIONS__): Define if not defined. (_REENTRANT): Remove. It has undesirable consequences in Solaris 2.6 (e.g. it turns off the putc macro). Defining __EXTENSIONS__ makes localtime_r and gmtime_r visible, which is what we want. * time/strftime.c: Likewise. 1998-09-08 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/dl-error.c: Fix spelling. 1998-09-08 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * stdlib/strfmon.c: Quiet -Wparentheses warnings. * stdio-common/_itoa.c: Likewise. * stdio-common/printf_fp.c: Likewise. * stdio-common/vfscanf.c: Likewise. * wcsmbs/wcstok.c: Likewise. * sysdeps/generic/glob.c: Likewise. * posix/getopt.c: Likewise. * sysdeps/posix/getaddrinfo.c: Likewise. * posix/wordexp.c: Likewise. * io/ftw.c: Likewise. * io/fts.c: Likewise. * misc/getpass.c: Likewise. * iconv/gconv_conf.c: Likewise. * argp/argp-fmtstream.c: Likewise. * argp/argp-help.c: Likewise. * elf/dl-load.c: Likewise. * locale/programs/stringtrans.c: Likewise. * catgets/gencat.c: Likewise. * posix/getconf.c: Likewise. * iconv/gconv_conf.c: Likewise. * iconv/iconv_prog.c: Likewise. * string/strcoll.c: Optimize a few expressions. * string/strxfrm.c: Likewise. 1998-09-08 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/dl-open.c (dl_open_worker): Move decl of new_global up one level to avoid uninit variable warning. 1998-09-09 10:34 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> instead of _dl_default_scope[2] as argument to _dl_init_next. Fix compatibility problems introduced in last change.
