Casting function pointers depends on the representation of const char * and const void * being the same, which is likely but not guaranteed. It would be safer to have wrappers (one for rb_strcasecmp and one for irccmp) that can be passed to rb_dictionary_create without a conversion.

Since rb_strcasecmp is part of librb, librb could also provide this wrapper. The wrapper for irccmp will need to be in ircd/.

By the way, the unsafety is similar to the previous unsafety since the code in librb/src/dictionary.c calls the unprototyped function with two const void * in all cases. The change to a prototyped function adds checking to those calls.

This strcmp also needs a wrapper somewhere to fix the types.

rb_dictionary_element *original = rb_dictionary_add(dict, "test", "data1");

ok(original != NULL, MSG);
