Does `strip -S' reduce the size of `racket'? I don't have a PPC machine
handy, but I get a 7686107-byte executable for ARM, which turns into
2845517 bytes after `strip -S'.

To make the overall size smaller, then it's probably a matter of paring
down collections to just what you need. If you don't need GUI or
graphics, then starting with the "textual" distribution might be a good
starting point:

 racket-textual-5.3.3-src-unix.tgz


We're currently working on a new package system that will let us better
organize the core and make more useful layers --- but that's very much
a work in progress.

No idea. Do these two test sets run ok?:

 collects/tests/racket/optimize.rktl
 collects/tests/racket/unsafe.rktl
