+Subject: [PATCH 1/2] linebreak: Avoid implicit declaration of u8_mbtouc_unsafe
+ function
+
+GNULIB_UNISTR_U8_MBTOUC_UNSAFE tells the bundled unistr.h to
+provide a function prototype for u8_mbtouc_unsafe.  This prevents
+build failures with future compilers which do not support implicit
+function declarations.
+
+Upstream gnulib has split the linebreak module into multiple parts;
+it is hard to tell if it still has the same issue.

+Subject: [PATCH 2/2] t4k_menu: Fix passing incompatible pointer type
+
+First observed under Gentoo Linux with GCC 14, probably due to
+mismatching types between child (struct _xmlAttr *) and node.children
+(struct _xmlAttr *).
+
+Resulting in build errors such as
+t4k_menu.c:254:23: error: assignment to 'xmlAttr *' {aka 'struct _xmlAttr *'} from incompatible pointer type 'struct _xmlNode *' [-Wincompatible-pointer-types]
+  254 |             for(child = node->children; child; child = child->next) {
+      |                       ^
+t4k_menu.c:256:62: error: passing argument 1 of 'menu_TranslateNode' from incompatible pointer type [-Wincompatible-pointer-types]
+  256 |                     tnode->submenu[i++] = menu_TranslateNode(child);
+      |                                                              ^~~~~
+      |                                                              |
