You can also declare the function correctly in the ASM source so it can be
interfaced by C++ progs. I remember that you have to append a specification of
the expected parameters to the name (something like GLOBAL _Test_V, V stands
for void. Sorry, I don't know exactly anymore, but I guess the documentation
should help you).
