Dimitry Andric 48cea5704f net/samba416: fix rl_completion_func_t detection and usage ... After a recent devel/readline update, net/samba416 fails to compile with clang 19, resulting in errors similar to: ../../libcli/smbreadline/smbreadline.c:139:38: warning: 'CPPFunction' is deprecated [-Wdeprecated-declarations] 139 | rl_attempted_completion_function = RL_COMPLETION_CAST completion_fn; | ^ ../../lib/replace/system/readline.h:50:31: note: expanded from macro 'RL_COMPLETION_CAST' 50 | # define RL_COMPLETION_CAST (CPPFunction *) | ^ /usr/local/include/readline/rltypedefs.h:38:50: note: 'CPPFunction' has been explicitly marked deprecated here 38 | typedef char **CPPFunction (void) __attribute__((deprecated)); | ^ ../../libcli/smbreadline/smbreadline.c:139:36: error: incompatible function pointer types assigning to 'rl_completion_func_t *' (aka 'char **(*)(const char *, int, int)') from 'CPPFunction *' (aka 'char **(*)(void)') [-Wincompatible-function-pointer-types] 139 | rl_attempted_completion_function = RL_COMPLETION_CAST completion_fn; | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There are two reasons: samba checks for `rl_completion_t`, while the actual readline type is `rl_completion_func_t`, and samba's wrapper `readline.h` header prefers the `CPPFunction` type which is deprecated, while it should use `rl_completion_func_t` instead. Fix the `wscript_configure` check to detect `rl_completion_func_t`, and reverse the `HAVE_RL_COMPLETION_T` and `HAVE_CPPFUNCTION` checks in the wrapper header.
