OK. Inability to use a tool shouldn't be blamed on the tool.

Eh. Yeah, exactly, that's the point. Type safety was _very_ important in the
design and evolution of C++, and so was the ability to work with current linker
technology, to be able to cooperate with other languages. Of course you lose
type safety when specifying C linkage. That is exactly what it means, in fact.
But since you don't have type safety in C in general, there is no loss. It's
just an extra feature. It's like "you can interface with all sorts of languages
if you want, but of course if the linkage required for that language isn't
typesafe, it wont suddenly become so when used from C++". I really don't see
this as a problem in practice. I very rarely interface with C or assembly
language to any larger degree, and if I do, I will make a typesafe interface
from C++ first.
