[Dovecot] Error compile dovecot 1.1.16

[Yanmarshus]

/* sorry, my english is bad :-( */

There's error i found while compile dovecot 1.1.16
Compiling run on Slackware 12.2 (fresh install)

Error in src/dict/main.c line 85 and line 102
   dict_drivers_register_all();
and
   dict_drivers_unregister_all();

I know C so little, and try to add these line to dict.h

void dict_drivers_register_all(void)
void dict_drivers_unregister_all(void)

After this patch, compiling run without error
My question, is that right solution ?

Thanks.
