From 564210fe2fdf88dd0800590b256cdb0751da1dec Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 10 Jun 1996 09:41:16 +0000 Subject: Mon Jun 10 02:22:24 1996 Roland McGrath * sysdeps/unix/sysv/linux/configure.in: New file, start with configure. Add check for installed being v2.0 or later. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill): Call __open instead of open. (_dl_sysdep_fatal): Call __write instead of write. (_dl_sysdep_message): Likewise. Sun Jun 9 20:40:00 1996 Andreas Schwab * sysdeps/m68k/fpu/e_acosl.c: New file. * Makerules (o-objects): New variable. Use it in place of $(objects:.o=$o); it filters out $(elide-routines$o). Use o-iterator for ar and ranlib rules so they use the per-type object list. * sysdeps/unix/bsd/ultrix4/sys/mman.h: Likewise. --- sysdeps/unix/bsd/ultrix4/sys/mman.h | 3 ++- sysdeps/unix/sysv/linux/configure | 39 +++++++++++++++++++++++++++++++++++- sysdeps/unix/sysv/linux/configure.in | 25 +++++++++++++++++++++++ 3 files changed, 65 insertions(+), 2 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/configure.in (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/bsd/ultrix4/sys/mman.h b/sysdeps/unix/bsd/ultrix4/sys/mman.h index d49da02..d929ca9 100644 --- a/sysdeps/unix/bsd/ultrix4/sys/mman.h +++ b/sysdeps/unix/bsd/ultrix4/sys/mman.h @@ -1,5 +1,5 @@ /* Definitions for BSD-style memory management.
