It would be better to declare and import them as C interfaces. To link
with C++ simply wrap each C interface in a 'static inline' function.
That will generate the correct inline C name whilst also performing
compile time parameter checking.

The only disadvantage is losing link time parameter checking. During
development you would need to manually change the asm function names (or
use a tool to extract them from a C++ file) so it may not be worth
worrying about.
