Why do you think this is ill-formed? Using a type with internal linkage as the type of an extern "C" function is explicitly permitted by the C++ standard. [basic.link]p8 says:

"A type without linkage shall not be used as the type of a variable or function with external linkage unless the entity has C language linkage [...]."
