+Subject: [PATCH] backends: use <sys/uio.h> instead of <linux/uio.h> for struct
+ iovec
+
+Since commit 0e8b57a3 ("elfcompress: Handle existing output files
+(symlinks)") lib/system.h includes <fcntl.h>.  When _GNU_SOURCE is
+defined, glibc's <fcntl.h> pulls in <bits/types/struct_iovec.h> (via
+bits/fcntl-linux.h), which defines struct iovec.  The kernel UAPI header
+<linux/uio.h> defines struct iovec unconditionally, so including it
+after "system.h" now breaks the aarch64 backend build:
+
+  In file included from aarch64_initreg.c:36:
+  /usr/include/linux/uio.h:17:8: error: redefinition of 'struct iovec'
+     17 | struct iovec
+        |        ^~~~~
+  In file included from /usr/include/aarch64-linux-gnu/bits/fcntl-linux.h:38,
+                   from /usr/include/aarch64-linux-gnu/bits/fcntl.h:61,
+                   from /usr/include/fcntl.h:35,
+                   from ../lib/system.h:42,
+                   from aarch64_initreg.c:33:
+  /usr/include/aarch64-linux-gnu/bits/types/struct_iovec.h:26:8: note: originally defined here
+
+Seen building 0.196 on aarch64 with glibc 2.39 and gcc 13.3.0.
+
+Both files only need struct iovec to call ptrace (PTRACE_GETREGSET),
+which glibc provides in <sys/uio.h>; that header guards the definition
+with __iovec_defined, so it composes with the rest of system.h.
+arm_initreg.c does not currently include "system.h" and so still builds,
+but it has the same latent conflict.
+
+* backends/aarch64_initreg.c: Include <sys/uio.h> instead of
+  <linux/uio.h>.
+* backends/arm_initreg.c: Likewise.
