Richard Suchenwirth 2007-10-09 - tcltcc is a Tcl extension wrapping tcc (the tiny C compiler), which was modified by MJ so it:
LGPL, download at http://code.google.com/p/tcltcc/ .
Like Odyce, it also comes with a Critcl emulation, so hopefully (at least some time in the future) people can just code against Critcl and run it with any of the three :^)
For one example usage, see ci - a tiny C interpreter.
MJ 2007-10-09 - Tclcc now also builds and works (passes the testsuite) on Linux
