+From: Jean Delvare <jdelvare@suse.de>
+Subject: compat/getopt: Handle a second separator
+
+getopt can be passed 2 '--' separators. The first one tells that
+getopt options are over and target program options start. The second
+one tells that the target program's options are over and following
+arguments should be treated as non-options even if they look like
+options.
+
+This second separator was not handled, causing the compatibility
+getopt script to treat the following arguments as options, eventually
+failing one way or another.
+
+Properly detect and handle the second separator. This fixes the first
+half of bug #54772:
+https://savannah.nongnu.org/bugs/index.php?54772
