+Subject: [PATCH] src/exec_ptrace: fix build without precess_vm_readv()
+
+Commit 32f4b98f6b4a (sudo frontend: silence most -Wconversion warnings.)
+broke the build on C libraries that miss process_vm_readv(), like
+uClibc-ng.
+
+Indeed, the ssize_t nwritten is declared guarded by HAVE_PROCESS_VM_READV,
+but is then re-assigned and used a few lines below, outside any guard.
+
+Fix that by always declaring the object, as it is always needed.
+
