I think there was a discussion about linking C++ objects, but I could
not find in the archive.  I thought that one way is to use -cc option,
but making the linker have correct options may not be easy.  Anything
else?

P.S. I use OMake, but OMake does not support mixing C++ and OCaml.  I
looked to OCamlProgram function's source to modify it, but I do not
find it.  Is it implemented by OCaml?  (not OMake script?)

The whole transcription is the following.  Sorry for the lengthy
message.
