Considering the availability in a default build I think it is the
intention for callcc to stay there. That is only a guess though.

Right now callcc seems to have a _large_ negative performance gap in
regard to the 1.8 implementation (tested on OS X, I'll try another OS
when I get a chance) so I am not sure I would use them in their
current state. Are there plans to address performance (or am I the
only one getting this problem)?
