This isn't what 'extern "C"' means. It changes the low-level name of functions
so that they can be conveniently called from C code, but the source inside an
'extern "C"' block is still normal C++. It can use the usual C++ style casts
and there's no more (or less) reason to prefer the old-style ones.

Also, this warning has to be enabled manually (it's not even in -Wall) so I see
no reason to change its behaviour inside that kind of block.
