2003-07-31 Jakub Jelinek <jakub@redhat.com> * dlfcn/dlerror.c (once): New. (dlerror): Call __libc_once. (_dlerror_run): Remove once. 2003-07-31 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext): Sync with 2.5.7 and 2.5.73 kernel changes. 2003-07-31 Jakub Jelinek <jakub@redhat.com> * dlfcn/eval.c (funcall): Add noinline attribute to shut up warnings. * elf/rtld.c (dl_main): Cast ElfW(Addr) arguments with %Zx/%Zd formats to size_t. * elf/dl-lookup.c (_dl_debug_bindings): Likewise. * elf/tst-tls6.c (do_test): Use %zd format for l_tls_modid. * elf/tst-tls8.c (do_test): Use %zd format for modid1 and modid2. * gmon/tst-sprofil.c (main): Add parens to shut up warning. * iconv/tst-iconv3.c (main): Use %td instead of %zd for pointer difference argument. * stdio-common/tst-wc-printf.c (main): Cast arguments with %C format to wint_t. * stdlib/tst-limits.c (main): For WORD_BIT and LONG_BIT, use %d format and cast expected value to int. * sysdeps/generic/libc-start.c (STATIC): Add __attribute__((always_inline) if LIBC_START_MAIN is already defined. * sysdeps/powerpc/fpu/w_sqrt.c (a_nan, a_inf): Change from uint32_t to ieee_float_shape_type. (__sqrt): Avoid type punning. * sysdeps/powerpc/fpu/w_sqrtf.c (a_nan, a_inf): Change from uint32_t to ieee_float_shape_type. (__sqrtf): Avoid type punning. * sysdeps/s390/s390-32/dl-machine.h (elf_machine_rela): Don't define refsym if in dl-conflict.c. * sysdeps/s390/s390-64/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/unix/sysv/linux/i386/semctl.c (union semun): Add __old_buf. (__new_semctl): Shut up warning. * sysdeps/unix/sysv/linux/semctl.c (union semun): Add __old_buf. (__new_semctl): Shut up warning. * sysdeps/unix/sysv/linux/shmctl.c (__new_shmctl): Wrap long lines. Change old into union of __old_shmid_ds and __old_shminfo structs. Adjust all users. * wcsmbs/wcsmbs-tst1.c (main): Cast arguments with %C format to wint_t. 2003-07-31 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/utimes.c (__utimes): Fix actime and modtime computation. * sysdeps/unix/sysv/linux/futimes.c (__futimes): Likewise. * sysdeps/posix/utimes.c (__utimes): Likewise.
