Thanks, this is the 'gcac' flag, right?
What if I build with "assert,df,fold,rtl,misc,tree,gc,rtlflag,runtime", would
that build within a reasonable amount of time?
And is it worth to build with more checking, than those enabled by default?
[i.e. did that expose bugs in the past?]

Rtl checking is also expensive (no way near as expensive as gcac) but
it does find real bugs in some cases. Everything else is enabled by
default during development of the trunk.

RTL checking is in fact moderately expensive, I use it all the time. But fold
checking is quite expensive and *not* enabled by default.
