r19132: Fix some C++ warnings. Is there interest to have them in Samba4 as well?

I have some problems resolving the last 3 ones in attrib_handlers.c. In line
251 the function ldb_dn_explode_casefold is called with mem_ctx as the first
argument. Looking at ldb_dn_explode_casefold I see that the first argument it
expects is a struct ldb_context. I could certainly add a cast to (struct
ldb_context *) to that call, but I would assume that this is the wrong fix. Is
it possible that attrib_handlers.c:251 and :254 should have ldb and not
mem_ctx as the first argument?

Can anybody from Samba4 clarify this for me and apply the correct fix?

Thanks a lot.

Volker
