ls -l busybox_unstripped
-rwxr-xr-x  1 landley landley 1075109 2006-06-15 15:24 busybox_unstripped
ls -l busybox
-rwxr-xr-x  1 landley landley 893112 2006-06-15 15:24 busybox

That's defconfig, built with gcc 4.0.3, _without_ build-at-once mode.

But when I do "size busybox" I also get 1.5 megabytes, which I'm guessing is 
mostly prezeroed bss data?  In which case the union of global structures 
should really help here...  In 1.3. :)
