From dff14448f7521b27349af4e67d141aba1c9d7edd Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 26 Jun 1998 14:47:05 +0000 Subject: Update. 1998-06-26 14:37 Ulrich Drepper * configure.in: Check for -fexceptions. * config.make.in: Define exceptions, not no-exceptions. * misc/sys/cdefs.h: Define __PMS. When using modern g++ define __P to use throw(). * misc/Makefile: Define CFLAGS-tsearch.c and CFLAGS-lsearch.c to $(exceptions). * stdlib/Makefile: Likewise for bsearch.c, msort.c, and qsort.c. * misc/search.h: Use __PMS in tsearch, tfind, tdelete, twalk, tdestroy, lfind, and lsearch prototpypes. * stdlib/stdlib.h: Likewise for bsearch and qsort. 1998-06-26 Ulrich Drepper * sysdeps/i386/fpu/bits/mathinline.h (__finite): Use C code, not asm. 1998-06-25 Andreas Schwab * Makefile (remove-old-headers): Make phony. * configure.in: Substitute @old_glibc_headers@. 1998-06-26 Ulrich Drepper * libc.map: Remove __libc_uid. 1998-06-24 Andreas Schwab * manual/terminal.texi (Allocation, Pseudo-Terminal Pairs): Fix typos. 1998-06-26 Ulrich Drepper * libc.map: Add Alpha-specific io function from protected namespace. --- misc/Makefile | 3 +++ misc/search.h | 38 +++++++++++++++++++------------------- misc/sys/cdefs.h | 14 +++++++++++++- 3 files changed, 35 insertions(+), 20 deletions(-) (limited to 'misc') diff --git a/misc/Makefile b/misc/Makefile index 52bf339309..9365fd2a1a 100644 --- a/misc/Makefile +++ b/misc/Makefile @@ -63,6 +63,9 @@ gpl2lgpl := error.c error.h tests := tst-dirname tst-tsearch tst-fdset tst-efgcvt tst-mntent +CFLAGS-tsearch.c = $(exceptions) +CFLAGS-lsearch.c = $(exceptions) + include ../Rules $(objpfx)libbsd-compat.a: $(dep-dummy-lib); $(make-dummy-lib) diff --git a/misc/search.h b/misc/search.h index 2258ce9d3a..96b28e3f98 100644 --- a/misc/search.h +++ b/misc/search.h @@ -127,22 +127,22 @@ VISIT; /* Search for an entry matching the given KEY in the tree pointed to by *ROOTP and insert a new element if not found. */ -extern void *tsearch __P ((__const void *__key, void **__rootp, - __compar_fn_t compar)); -extern void *__tsearch __P ((__const void *__key, void **__rootp, +extern void *__tsearch __PMS ((__const void *__key, void **__rootp, + __compar_fn_t compar)); +extern void *tsearch __PMS ((__const void *__key, void **__rootp, __compar_fn_t compar)); /* Search for an entry matching the given KEY in the tree pointed to by *ROOTP.
