Hello,

detection of HAVE_MYSQL_SSL_VERIFY_SERVER_CERT is currently broken, and the macro is never defined. The test program fails, but for incorrect reason.

--8<---------------cut here---------------start------------->8--- conftest.c:140:20: error: expected declaration specifiers or '...' before ',' token 140 | _au_m4_changequote(,) | ^ conftest.c:140:21: error: expected declaration specifiers or '...' before ')' token 140 | _au_m4_changequote(,) | ^ In file included from /gnu/store/6lmd3apzkmhwzj3yn0inyj484m9qml6y-mariadb-connector-c-3.4.5/include/mariadb/mysql.h:35, from conftest.c:141: /gnu/store/7iwcvd0gjrfq6bj7zvf3r59baw6vib5a-gcc-14.3.0-lib/lib/gcc/x86_64-unknown-linux-gnu/14.3.0/include/stdarg.h:103:9: error: unknown type name '__gnuc_va_list' 103 | typedef __gnuc_va_list va_list; | ^~~~~~~~~~~~~~ --8<---------------cut here---------------end--------------->8---

Fix is to delete the only occurrence of _au_m4_changequote([,]) in the m4/want_mysql.m4 file.

However, that will reveal a compilation error here:

--8<---------------cut here---------------start------------->8--- #ifdef HAVE_MYSQL_SSL_VERIFY_SERVER_CERT int ssl_verify_server_cert = ssl_set->ssl_client_require_valid_cert ? 1 : 0;

	mysql_options(db->mysql, MYSQL_OPT_SSL_VERIFY_SERVER_CERT,
		      (void *)&ssl_verify_server_cert);

#endif #else --8<---------------cut here---------------end--------------->8---

Variable ssl_set' does not exist and should be db->ssl_set'.

Have a nice day, Tomas Volf
