Yes.
The linux symbol tells you the exact, correct argument types (or type, in this case) and order (aside from the thisptr). The rest is due to the return type.
If you were to figure out the struct and add it to the code, and putting it as the return type, the compiler on each platform would generate exactly what you are seeing.
