I'm not sure yet that this would fix the specific issue, but we can kind of reverse which declaration is the alias and which is the aliasee, which ends up being fewer lines of code in the macro:

Though that would mean replacing the declaration in `libc/src/<hname>/<fname>.h` from being within `LIBC_NAMESPACE` to being `extern "C"`, and same for the defintion in `libc/src/<hname>/<fname>.h`, en masse.
