Regarding "Access to C-only functions", you say that it's
necessary to write C++ wrappers to call the C functions.

I don't see why that should be necessary as long as the
declarations are in an "extern from" block and the header
file encloses them in 'extern "C"'. Then the C++ compiler
will know that they are C functions and generate the
appropriate linkage for calls to them.
