+Subject: [PATCH] Switch getrandom() and arc4random_buf() usage order
+
+We need to match the order of inclusions at the top of the file
+otherwise we might end up trying to use arc4random_buf() when
+available (because HAVE_ARC4RANODM_BUF is set) even though
+we hit HAVE_GETRANDOM first above and only included
+<sys/random.h> because of it.
+
+Besides, if getrandom() is available, we should really prefer
+it anyway.
+
+Fixes an implicit function declaration:
+```
