Nothing except more speed (1 GHz vz ~200 MHz, 1 GB RAM vz 32 MB + 64 MB
swap (to a cardflash card, no less), compiling over a usb 1.1 nfs mount
... it took *a while* to compile ecl :), and a more up-to-date compiler
(3.3 vs 2.95.3).  I found a webpage on compiling the whole cross-compiler
toolchain from scratch, but haven't had time to try it (or the motivation,
given that my 2.95.3-compiled version works acceptably so far).

Thanks, I'll try that.  I'd seen that suggestion in the manual or readme
or somewhere, but postponed it.
