+Subject: [PATCH] Fix Clang 16 errors for invalid C99 constructs
+ (-Wincompatible-pointer-types)
+
+These errors were caused by `t_title` function having "void" parameter
+instead of "ui_tab_t *tab", like everywhere else:
+
+```
+src/uit_conn.c:398:41: error: initialization of char * (*)(ui_tab_t *) from incompatible pointer type char * (*)(void) [-Wincompatible-pointer-types]
+  398 | ui_tab_type_t uit_conn[1] = { { t_draw, t_title, t_key, t_close } };
+      |                                         ^~~~~~~
+```
+
+Also renamed `t` param in `t_title` of "src/uit_main.c" to `tab`,
+for consistency with other functions.
+
+This error appeared only in 1.24 release cycle, because changing
+prototypes from "()" to "(void)" in 2cf47a7ec9f35d1afaf24a6f9644fbecf6df92df
+changed meaning of the type from "any parameters, including ui_tab_t *"
+to "no parameters at all", and this is where Clang starts to complain.
