There is apparently a nasty problem with kaffe on xscale: the assembler 
code in config/arm directory uses some instructions for doubles and 
floats that aren't available on xscale, afaik.

Ah, okay. See http://www.kaffe.org/doc/kaffe/FAQ.cross-compiling . You 
need to have kaffe build and installed on the build platform, in order 
to use the local kaffeh.

quoting from the document:

"It does not work!
=================
The way how to supply options to configure is roughly ok, but it is
not enough. Because, include files needed to compile some library
files are generated automatically while build, and 'jar' file is
also generated while build. These files need runnable (on build computer)
'kaffeh' and 'kaffe' to generate.

To do that, you first have to make and install 'native' kaffe, and
totally you may have three directories. In this document I use
'kaffe-1.1.0' where you store the source code, 'kaffe-native' where
you make native kaffe, and 'kaffe-m68k-linux' where you make cross
compiled kaffe.

Then, you have
   . --- kaffe-1.1.0
      +- kaffe-native
      +- kaffe-m68k-linux
and, you first visit 'kaffe-native' and do '../kaffe-1.1.0/configure' and
'make; make install' first. Then you copy generated 'rt.jar' in somewhere
by
   cp libraries/javalib/rt.jar /tmp/rt.jar

And then, you can

   CC=m68k-linux-gcc NM=m68k-linux-nm AR=m68k-linux-ar \
	../kaffe-1.1.0/configure --host=m68k-linux --build=i686-linux \
	--with-rt-jar=/tmp/rt.jar
"

Of course, this raises the question whether we should not simply check 
in the header files into CVS to make it easier to (cross-)compile kaffe 
since that seems to be a regular stubling block.

I'll put up a snapshot of CVS tomorrow, and send you a link. I'm just 
running late for a bis right now :(

i hope this helps a little,

cheers,
