RRS had considered building such a tool commercially early on during the
development of Ada 9x (possibly as part of the development of what became
Claw). But the existence of c2ada made it likely that such a tool would not
produce a lot of revenue, and we decided it we didn't need it for Claw. So
we didn't do it.
The thin bindings created by something like C2Ada don't buy you much anyway:
they're at least as hard to use as the C code, impossible to debug
(especially when something caused a mismatch of parameters), and don't do
much to show off the advantages of programming in Ada. Programming with them
is like writing C in Ada syntax. To make them usable, you have to wrap them
in a real Ada package - but then you might as well have built the whole
thing by hand. Which is why we built Claw...
