[R] .C() and C++ name mangling

        I'm working with some external code written in C++, which I
        would like to call via dyn.load() and .C() from R.  The
        function prototype looks like:

        gaRemin(int *, float *, float *, int *, float *, float *, 
                float *, float *, float *)

        but to call this function from R using .C() I have had to use
        the mangled version of this function name,


        Is using the mangled name my best option, or is there some way
        that R knows to interpret unmangled function names from C++
        shared library objects?

        I'm concerned about portability of the resultant code in the
        case that name-mangling is handled differently from platform
        to platform.

        This is Linux, Redhat 7.2 with g++-2.96.

        Thanks for any help you can offer,
