Compiler?

[ET]

What compiler should we use?

At LMI, we ported the Yale T compiler.  We retargeted the
back end for K-machine native code (it was a horror), and
we retargeted the front end for CommonLisp (mostly trivial,
except for PROGN).

Preferably, it would be written in Lisp, support general tail
recursion, produce reasonably tight code, be able to
generate fairly independent executables, and allow the
user to drop in LAP or i386 instructions or primops or
something.
