Neither does Tcl's critcl AFAIK (I think it just sticks the C code in a Tcl extension and compiles it using the system compiler). My intent there was just to list cases where wrapping a whole C/C++ library is unnecessary, not to imply that Julia uses libffi :)

On that note, LLVM helps a lot here, too. Are there any LLVM-based languages that don't have some degree of C compatibility?

Parse error on my part, excuse the pedantry :) Tcl is such a weird and wonderful language, and I occasionally miss it (though I don't miss working with a GUI written in C++ wrapped around tk).
