There isn't anything interwined with Swarm w.r.t. to Kaffe, but I
suspect your intent is to run with minimal dependencies from the Swarm
development kit, i.e. all the Unix development stuff.  The dependencies
for javaswarm.dll can be seen using:

$ objdump --all-headers /Swarm-2.1.1/bin/javaswarm.dll | grep 'DLL Name:'

They are cygwin1.dll, BLT24.dll, cygtcl80.dll, and cygtk80.dll.  These
files can also be found in /Swarm-2.1.1/bin.  The other DLL
dependencies are a part of Windows.

javaswarm.dll is for Sun JDK and libkaffeswarm.dll is for Kaffe.  The 
difference is due to a fairly minor variation in the way Jave Native Interface
is implemented.  javaswarm.dll and libkaffeswarm.dll are independent.

Also, you'll need the associated directories (by name) in /Swarm-2.1.1/share:
tcl8.0/, tk8.0/, blt2.4/, and swarm/.

It must be /Swarm-2.1.1/share, too.  That's not as big as a problem as
you might think because you can `mount' /Swarm-2.1.1 to be any path
you want.

Yes.  The only thing is that you have to be careful not to have
callbacks into Swarm from widgets.  Swarm isn't thread safe.  This
also is not a huge problem to code around if you think about it.  All
that is needed is an ordinary Java object to accept instructions
from Swing things, which Swarm can then picks up when it is ready.  By
"Swarm" I mean any feature from Swarm in the "swarm" Java package.
