Well, I don't see how this was guaranteed to work anyways. If `str` points to ro memory, you're hosed anyways. The C standard should fix these const -> non const issues at some point (as C++11/C++14 is finally doing). Is there a `strlchr` function floating around somewhere?

What you mean by that? Even C++98 requires std::strchr() and similar functions to be overloaded so that the return type matches the pointer argument type. I don't know how that could be achieved in C.

Well, the ideal fix's first step is "acquire time machine", but other than that, there's not much to be done other than something like a flag day (which I don't see happening any time soon), or adding overloading to C (somehow…), or CDR (C Done "Right") (which would never take off due to the incompatibilities).

If you're replying to the C++ side of things, it's most in reference to the fact that lots of container methods are now accepting const_iterator instead of iterator (such as erase() and insert()) so that you don't have to "infect" non-const-ness around to other places (or const_cast).

CDR exists. It's called Embedded C++: http://en.wikipedia.org/wiki/Embedded_C%2B%2B.

I always though ABC (A Better C) was a better name but, apparently, that's already taken.

Embedded C++ is very strange creature because it removes one of the most important advantages of C++: namespaces. Thing like a namespace is more-or-less required to manage large programs and Embedded C++ forced the same fourty years old substitute (prefixes and/or suffixes).

Frankly I don't see a point. It's not really compatible with C++, but it's not compatible with C either. It includes not usable rounded-up set features but bunch of easily implementable features instead. In short: it's something designed to brag about, not something designed with real work in mind. Very similar to LSB: both in idea and in implementation. Only LSB has slowly started to acquire useful features recently, while EC++ just died.

Embedded C++ is a pathetic idiocy that remove tons of useful functionality without any reason and doesn't solve any of the real problems that C and C++ have. Quoting Stroustrup: "To the best of my knowledge EC++ is dead (2004), and if it isn't it ought to be." (http://www.stroustrup.com/bs_faq.html#EC++).

There is nothing done right about EC++, you'll have to try harder than that.
