Hm, there doesn't seem to be a runtime testcase attached to this bug, so I
can't produce numbers for the upcoming 4.6 release. Brad, can you do so
if you have time?
Thanks.
Btw, how difficult is it to setup a continuous performance testing of Gambit?
Is Gambit reasonably self-contained (no external dependenices,
commandline-driven)? I'm considering to add it to
http://gcc.opensuse.org/c++bench/
I probably can get it built but would appreciate hints on how to setup an
automated performance test.
