Many Ada compilers have little or no C in their runtime. There surely is
none in Janus/Ada (some assmbler, the rest is Ada), and my understanding is
that is also the case for several other compilers. But keep in mind that the
underlying OS (Windows for Janus/Ada) is probably written in C or something
even more error-prone. So what the Ada runtime is written in isn't likely to
have much effect on the reliability of the entire system.

We did once have a bare machine version of Janus/Ada (I know other companies
did too), but we dropped it for lack of demand. Almost every runs on some
sort of OS these days.
