Dear JCB,
I managed to compile MKCL from git, but only after I updated its ASDF.
Unless you have a good reason, I recommend you only include
a bootstrapped version of asdf.lisp in your source tree.
You should of course keep generating it from an asdf checkout,
and send us any local patch you create (thanks a lot for that!)
In 3.1.0.109, I have an attempt at implementing get-optimization-settings
on most implementations (allegro is still missing,
plus ecl-bytecmp, genera, corman, mcl);
my implementation for MKCL does not work and/or
proclaim does not work: c::*speed* exists but isn't updated by proclaim.
Can you help me fix that?
