Alcor6L people: This commit is the result of
a mistake in previous commits. Sorry.

I didn't realize I wasn't supposed to stage
this file. While working towards getting
adc.c to pass compilation with TinyScheme,
(obvious; gcc doesn't complain about the
unfinished function in picoLisp in TinyScheme
mode), I staged it and hit commit for all
platform generic modules :(
