Memory accounting (for `custodian-limit-memory', etc.) is now enabled
by default in the 3m variants of MzScheme and MrEd. In other words,
configuring with --enable-account is redundant.

If you need the old 3m collector for some reason, configure with
--enable-compact. As the name of this flag suggests, the old 3m
collector tends to keep a smaller memory footprint than the now-default
collector, but the difference between the two collectors is much less
significant than the difference between 3m "precise" collection and
conservative collection. The old collector does not support memory
