Hi!
Plus a few small other things.
$(uses-callbacks) is mainly so that it can be changed easily in one place.
2003-09-15 Jakub Jelinek <jakub@redhat.com>
* argp/argp.h (argp_parse, __argp_parse): Remove __THROW.
* argp/Makefile (CFLAGS-argp-help.c, CFLAGS-argp-parse.c): Add
$(uses-callbacks).
* dirent/Makefile (CFLAGS-scandir.c, CFLAGS-scandir64.c): Likewise.
* elf/Makefile (CFLAGS-dl-iterate-phdr.c,
CFLAGS-dl-iterate-phdr-static.c): Add $(uses-callbacks).
* elf/dl-iteratephdr.c (cancel_handler): New function.
(__dl_iterate_phdr): Add __libc_cleanup_{push,pop}.
* elf/link.h (dl_iterate_phdr): Remove __THROW.
* io/Makefile (CFLAGS-fts.c): Merge into one assignment.
Add $(uses-callbacks).
(CFLAGS-ftw.c, CFLAGS-ftw64.c): Add $(uses-callbacks).
* misc/Makefile (CFLAGS-tsearch.c, CFLAGS-lsearch.c): Change
$(exceptions) to $(uses-callbacks).
* Makeconfig (uses-callbacks): Set to $(exceptions).
* posix/Makefile (CFLAGS-glob.c, CFLAGS-glob64.c): Add
$(uses-callbacks).
* stdlib/Makefile (CFLAGS-bsearch.c, CFLAGS-msort.c, CFLAGS-qsort.c):
Likewise.
nptl/
* Makefile (CFLAGS-pthread_once.c): Add $(uses-callbacks).
linuxthreads/
* Makefile (CFLAGS-mutex.c): Add $(uses-callbacks).
(CFLAGS-sighandler.c): Change $(exceptions) into $(uses-callbacks).
