siginfo-arch.h is included in two different places, so the default definitions of the macros that it might or might not define need to be done conditionally afterward, not unconditionally beforehand. * sysdeps/unix/sysv/linux/bits/siginfo-consts.h (__SI_ASYNCIO_AFTER_SIGIO): Define default after including bits/siginfo-arch.h, only if not already defined. * sysdeps/unix/sysv/linux/bits/types/siginfo_t.h (__SI_ALIGNMENT, __SI_BAND_TYPE, __SI_CLOCK_T) (__SI_ERRNO_THEN_CODE, __SI_HAVE_SIGSYS, __SI_SEGFAULT_ADDL): Likewise. * sysdeps/unix/sysv/linux/ia64/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/mips/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/x86/bits/siginfo-arch.h: Unconditionally define __SI_* macros.
