From 68b506045507245594280b53e1ccdd425bc0a6a5 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 25 Mar 1998 15:21:09 +0000 Subject: Update. 1998-03-25 Ulrich Drepper * glibcbug.in: Create files safely when mktemp is not available. * sysdeps/unix/sysv/linux/adjtime.c: Make weak alias appear again. Patch by a sun . 1998-03-25 Thorsten Kukuk * libc.map: Rename getname to getnetname. 1998-03-25 13:35 Ulrich Drepper * manual/maint.texi: Use supported platform in examples. * manual/install.texi: Document some installation tips. 1998-03-25 10:56 Ulrich Drepper * posix/wordexp.c: Fix some memory leaks and makes $* more efficient. Fix a bug so that it returns an error if a numeric parameter is unset and WRDE_UNDEF is set. Patch by Andreas Schwab and Tim Waugh. * posix/wordexp-test.c: Add new new test. 1998-03-25 Ulrich Drepper * posix/regex.c (regex_compile): Last patch wasn't entirely correct. Patch by Alain Magloire . 1998-03-24 Andreas Schwab * manual/filesys.texi (Scanning Directory Content): Fix typo. 1998-03-25 09:24 Bernd Schmidt * sysdeps/i386/bits/string.h: Fix all assembler statements so that clobbered registers don't appear as operands. --- manual/maint.texi | 105 ++++++++++++++++++++++++++---------------------------- 1 file changed, 50 insertions(+), 55 deletions(-) (limited to 'manual/maint.texi') diff --git a/manual/maint.texi b/manual/maint.texi index b8ae488c2f..a7e0cc4b0a 100644 --- a/manual/maint.texi +++ b/manual/maint.texi @@ -296,74 +296,57 @@ these to pick the list of system-dependent directories to look for.
