Well, at least all of these:

- Scheme
- Haskell
- OCaml
- F#
- Erlang
- Clojure
- Some C and C++ compilers (gcc, Intel, MSVC in release mode)
- Most commercial Lisp compilers

Yes D compilers also do tail call optimizations in certain cases, 
even if not specified in the language spec, picking up an old 
thread
