-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-* src/sysdep.c (sigsegv_stack): Increase size to 64 KiB and align
-it to max_align_t. This copies from Gnulib’s c-stack.c, and works
-around a portability bug in draft glibc 2.34, which no longer
-defines SIGSTKSZ when _GNU_SOURCE is defined.

+Subject: [PATCH] Port alternate signal stack to upcoming glibc 2.34
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+* src/sysdep.c (sigsegv_stack): Increase size to 64 KiB and align
+it to max_align_t. This copies from Gnulib’s c-stack.c, and works
+around a portability bug in draft glibc 2.34, which no longer
+defines SIGSTKSZ when _GNU_SOURCE is defined.
