--wrap should work fine with C++.  However, you do have to mangle the
names yourself, and use --wrap with the mangled name.

There is no real alternative.  It is not practical for the linker to
incorporate a C++ mangler, particularly as different compilers, even
different versions of g++, use different mangling schemes.
