+Subject: [PATCH] readline/tcap.h: Update definitions for C23
+
+C23 changes how function definitions like int `int tputs ()` are
+interpreted. In older standards this meant that the function arguments
+are unknown. In C23 this is interpreted as `int tputs (void)` so now
+when we compile with GCC15 (which defaults to -std=gnu23) we get an
+error such as
+
+  readline/display.c:2839:17: error: too many arguments to function 'tputs'; expected 0, have 3
+
+Add the function arguments for tgetent(), tgetflag(), tgetnum(),
+tgetstr(), tputs() and tgoto().
