What's this based on (out of interest)? Most C compilers don't necessarily
identify tail recursion in *C* code but if you're emitting C as an OCaml
backend then there's no reason not to convert tail recursive *OCaml*
functions to C code based on goto or similar looping constructs (yes, you'd
almost-always-virtually-never use goto in a hand-crafted C program without
apologising profusely at Dijkstra's grave but if you're using C as an
intermediate language then that's a different matter). If I recall correctly
from an old post on this list, this is how Felix handles tail recursion when
translating Felix to C++
