+Subject: [PATCH 1/2] compat/systemd: Include <string.h> for strerror
+
+Recent compilers are getting stricter about function declarations being
+known during compilation and e.g. clang-15 now errors out if a function
+signature is not found:
+
+> compat/systemd.c:56:49: error: call to undeclared library function 'strerror' with type 'char *(int)'; ISO C99 and
+>       later do not support implicit function declarations [-Wimplicit-function-declaration]
+>                 xasprintf(cause, "systemd socket error (%s)", strerror(errno));
+>                                                               ^
+> compat/systemd.c:56:49: note: include the header <string.h> or explicitly provide a declaration for 'strerror'
+> 1 warning and 1 error generated.
+
+Provide the declaration of `strerror` by including `<string.h>` to fix
+this

+ warning

+clang-15 warns about the pointer passed to `getsockname()` being of
+different signedness then the parameter declaration:
