sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h. Fix grammar error in comment, if present. * bits/sigstack.h * sysdeps/unix/sysv/linux/aarch64/bits/sigstack.h * sysdeps/unix/sysv/linux/alpha/bits/sigstack.h * sysdeps/unix/sysv/linux/bits/sigstack.h * sysdeps/unix/sysv/linux/ia64/bits/sigstack.h * sysdeps/unix/sysv/linux/mips/bits/sigstack.h * sysdeps/unix/sysv/linux/powerpc/bits/sigstack.h * sysdeps/unix/sysv/linux/sparc/bits/sigstack.h * bits/sigcontext.h * sysdeps/mach/hurd/i386/bits/sigcontext.h * sysdeps/unix/sysv/linux/bits/sigcontext.h * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h * sysdeps/unix/sysv/linux/sparc/bits/sigcontext.h: Add multiple inclusion guard. Permit inclusion by sys/ucontext.h as well as signal.h, if this was not already allowed. Request definition of size_t if necessary. Minimize semantically-null differences across files.
