+Subject: [PATCH] Fix use of strchr with new GCC
+
+According to C specification, 7.28.5.1, strchr() is a generic function
+and its string argument's type is promoted to the result. So if it is
+const char*, the result will be const char* as well.
+
+gcc in Fedora Rawhide (15.2.1 20251111 or later) implements this
+conformance, resulting in a compilation fail with
+-Werror=discarded-qualifiers.
