I don't think "const" exists in all versions of C. My old C reference book
(circa 1984) doesn't list it as a reserved word, or anywhere at all for that
matter. I suspect that means it did not exist in K&R C. Was it introduced in
ANSI C? In C++?

I don't look at too much C code myself, but the first time I ever saw "const"
in C source was about 3 months ago, and it was for a C++ capable compiler.
