__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.
