People erroneously believe that and then freak out when they find it
isn't true.  Consider signed arithmetic overflow being twos-complement
arithmetic in PDP-11 assembly language, vs being undefined behavior in
C.  In Ada it's supposed to signal a constraint error iiuc.

So C wouldn't really be a natural target for an Ada compiler.  C is not
a "portable assembler" despite the wishes or dreams of some of its
users.
