I guess you're trying to implicate Ada here and contrast it with C (or
perhaps C++). Ada doesn't ban other languages -- there is still a lot of
effort going on to interface Ada to other systems and lnaguages. In general,
the problems don't actually come from Ada, but from poor specification in
other languages, notably C.

As someone else pointed out, many C interfaces use char * for everything and
then typecast to the type they really mean later on. This makes for a poor
and error prone interface spec. -- as I found out when writing an Ada
binding to Berkeley sockets. Is this an example of C's great tolerance?

Unfortunately, the motivations for choice are not as altruistic as you
perceive. Choice of computer languages, as in many other areas, has very
little to do with how good the language is technically. It has far more to
do with exposure, marketing and education.

Most of the choices are made at a superficial level -- after all, properly
evaluating the alternatives takes time, money and thought and making a
change from your current system takes a paradigm shift, retraining and
different and/or new ways of thinking.

How many companies properly perform this evaluation and are prepared to make
the changes for long term goals?
