Is there any such thing as extern "C++"? This must be a mistake in the 
sources?

I also hope not. C++Builder (or as the current name, Developer Studio) 
is an excellent RAD tool, and for the occasional apps that needs Ruby 
scripting it would be great if everything works. A couple of years ago, 
I had to use it Ruby in a C++ Builder project, googled about it and 
every discussion thread I searched about it ended in a kind of 
"uncertain" state. So I finally ended up building a custom DLL wrapper 
to the one-click version of the Ruby DLL library instead. Very 
time-consuming, since I had to re-prototype every Ruby C function I needed.
