configure.ac: check for stdarg.h Currently, there is the following compile error while building with -std=gnu23, which is now default for GCC 15: src/shared/shell.c: In function 'rl_cleanup': src/shared/shell.c:1435:9: error: too many arguments to function 'rl_message'; expected 0, have 2 1435 | rl_message("%s", ""); | ^~~~~~~~~~ ~~~~ In file included from src/shared/shell.c:29: /usr/include/readline/readline.h:410:12: note: declared here 410 | extern int rl_message (); | ^~~~~~~~~~ This adds a check for stdarg.h inside the configure script so that HAVE_STDARG_H gets defined and the correct prototype is picked from readline.h.
