@1: The limits are considered obsolete since C89 and implementations are encouraged to avoid them whenever possible. I think the same way we disregard non ASCII character sets, non two's complement encodings and similar, we are safe in assuming sane implementation being able to handle longer names. And being honest, if given implementation isn't capable of more than 31 significant characters, then it would have problems with namespaces too.
@2: Agree, although I don't recall this ever happening to me.
@3: Is it? How is libname::actual_function_name() much better?
I actually like to use libname__actual_function_name(), as it further separates "namespace" from function name (unless we need compatibility with C++, as IIRC it reserves all double underscores, not only at the beginning).
