If so I misread the original sentence. (But see below)  I took it to
mean that Zortech believed it had a language that was both C++ and
ANSI compatible. This is a very attractive idea and people who have
not looked at the technical issues often assume that it is easy to
achive.

The point is not whether you tell the compiler that it has a C or C++
program by the command name, by switches, by filename (or extensions)
or in some other fashion.  The point is that there are
incompatibilities and hence the compiler has to know if it is
compiling C or C++.

The point of the "of course" was that I thought the original poster
was copying from some Zortech literature rather than making comments
on the product, and that some readers (e.g. those who follow
net.lang.c) would understand the situation immediately  while others
(C programmers with just a casual interest in C++) might be mislead.
