Yes, this in the FAQ.

2.3.3. Compiler warnings. Even after patching Swarm, if you compiled it
with egcs/gcc you will get "harmless" warnings at compile time about
objective-C symbols being undefined. This is a long standing flaw in the
egcs/gcc that Marcus Daniels has corrected. (see
http://www.santafe.edu/projects/swarm/archive/list-archive.9905/0069.html).
You can patch your egcc and recompile it and Swarm to make the warnings
go away. 

The most recent version of marcus's patch is in the swarm ftp site in a
directory with a name like needed-software/patches.

The RPMS distributed by SFI are not built with a patched version of GCC,
so they cause those messages too.
