How to deal with GCC built-in functions?

22:52 <bddebian> We need prototypes for memcpy and memset in gnumach.  It would alleviate alot of build warnings.
22:53 <antrik> in the linux drivers or in gnumach itself?
22:54 <bddebian> gnumach itself
22:54 <bddebian> I'm trying to find a "global" header file to stick them in :-)
22:55 <bddebian>  port.h maybe
22:56 <antrik> do these functions exist anywhere in the source, or does it rely on compiler builtins?...
22:56 <bddebian> They are implicetly defined in several programs
22:57 <bddebian> ipc_entry.c for example:
22:57 <bddebian>         if (!it_entries_reallocable(oits))
22:57 <bddebian>             (void) memcpy((void ) table, (const void ) otable,
22:57 <bddebian>                   osize * sizeof(struct ipc_entry));
23:14 <bddebian> So, since all you guru's are here, what header file should I put prototypes for memcpy and memset in? :-)
23:15 <marcus> oh you are writing an allocator? :)
23:15 <marcus> malloc.h
23:15 <marcus> oh
23:16 <neal> memcpy and memset are usually in string.h
