+Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
+
+Current glibc no longer gives the ucontext_t type the tag struct
+ucontext, to conform with POSIX namespace rules.  This requires
+various linux-unwind.h files in libgcc, that were previously using
+struct ucontext, to be fixed to use ucontext_t instead.  This is
+similar to the removal of the struct siginfo tag from siginfo_t some
+years ago.
+
+This patch changes those files to use ucontext_t instead.  As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.
+
+Tested compilation together with current glibc with glibc's
+build-many-glibcs.py.

+This patch changes those files to use ucontext_t instead.  As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.
+
+Tested compilation together with current glibc with glibc's
+build-many-glibcs.py.
+
+	* config/aarch64/linux-unwind.h (aarch64_fallback_frame_state),
