Thanks, that worked nicely. What needs done to make the generational GC 
work on a new platform? (this is a horribly RAM-starved platform, 
bearing in mind that it's running full X11 etc. in 128M, so I can see 
the GC having a fair bit of work to do. :) )

Thanks for this one too. Turned out that gen.lispbibl.c was generated 
empty, which was caused by busybox's sed not liking the regexps in the 
Makefile much. Oddly it ran OK, but deleted the contents of every line 
from the output except the header #line tag. I just installed regular 
GNU sed and it straightened that out with no further complications.

In fact, despite vacall-arm being broken, it managed to compile at least 
enough of the FFI bits and pieces for readline to work (the module seems 
to depend on the existence of it - certainly it didn't compile when 
set up with configure --without-dynamic-ffi. The defpackage in 
readline.lisp says it uses (:use "CL" "EXT" "FFI"))

So, for future reference for anyone else trying to get it going on 
small ARM linux platforms:

CFLAGS="-DNO_GENERATIONAL_GC" and install GNU sed is all it takes 
to get 
it to work on the Nokia N800. There are no particular configure options 
needed to make it work. 

Oh, and without -DSAFETY we get:

Test passed.

real    5m28.941s
user    4m58.844s
sys     0m13.234s

Not too shabby - I guess debugging adds about 10 seconds to that time 
normally.

Thanks again for your help,
