+Subject: [PATCH] Fix build with mysql-connector-c v8.0.18
+
+This fixes following compilation failure with version 8.0.18 of
+mysql-connector-c:
+```
+rdf_storage_mysql.c: In function 'librdf_storage_mysql_get_handle':
+rdf_storage_mysql.c:450:5: error: unknown type name 'my_bool'; did you mean 'bool'?
+  450 |     my_bool value=(context->reconnect) ? 1 : 0;
+      |     ^~~~~~~
+      |     bool
+make[3]: *** [Makefile:886: librdf_storage_mysql_la-rdf_storage_mysql.lo] Error 1
+```
+
+The correct type for calling `mysql_options` with `MYSQL_OPT_RECONNECT`
+in version 8.0 of the library is `bool*`:
