A 1.0.1 bug fix release for ThinLisp has just been made available. This release fixes some issues when running the ThinLisp Lisp to C translator within CMU Common Lisp as a host environment. At this point the translator has been tested in CLISP, CMU Lisp, Allegro, and MCL. Users have reported trying it in SBCL, and there are edits here that will hopefully resolve issues within that implementation.
Meanwhile, work continues on the 1.1 release, working towards lexical closures and support for pthreads.
