From a2c396f8a991e93cd606fdb9e3b4ca91fa652730 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 3 Sep 2002 02:45:12 +0000 Subject: [PATCH] * sysdeps/powerpc/elf/libc-start.c [! SHARED]: Call __pthread_initialize_minimal and __libc_check_standard_fds to match the generic version. * sysdeps/powerpc/Makefile (CFLAGS-pt-initfini.s): New variable. * sysdeps/unix/sysv/linux/shmat.c (shmat): Add a cast to avoid a warning when INLINE_SYSCALL macro uses the __syscall_ipc function. * locale/localeconv.c (__localeconv): Cast -1 to char to avoid warnings on platorms where char is unsigned. --- ChangeLog | 14 ++++++++++++++ sysdeps/powerpc/Makefile | 5 +++++ sysdeps/powerpc/elf/libc-start.c | 34 +++++++++++++++++++++++++++++++--- sysdeps/unix/sysv/linux/shmat.c | 5 +++-- 4 files changed, 53 insertions(+), 5 deletions(-) diff --git a/ChangeLog b/ChangeLog index 5d2b6cc..bc51375 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,17 @@ +2002-09-02 Roland McGrath + + * sysdeps/powerpc/elf/libc-start.c [!
