My experience is not very extensive, so please correct me if I am wrong.
The biggest problem I have seen with C++ is binary incompatability  between 
libraries and applications using them. This is actually not that much of a 
problem for me, just the nuisance that upgrading the compiler means 
recompiling all my C++ libraries. And I don't upgrade my compiler that 
often :)

But for distributing binaries of programs using a shared libcsound it is a 
real problem. The program won't run if it was compiled for a libcsound 
compiled differently. Even a different optimization flag will break binary 
compatibility I think. The only solution is to distribute a statically linked 
private copy of libcsound with your application. 
So I think that the ambition of csound5 as a platform independent library is 
best served by it being pure C.

(And yes, I think including widgets in core Csound5 was/is a mistake. For one 
thing it assumes that csound will only be run on general purpose pc's, and 
that as long as you support windows, Mac and linux you are cross platform. My 
cell phone has a 400 MHz processor and stereo sound. Csound should run on 
that, and it will but without the widgets. Including C++ and widgets in the 
core csound, will just create a forks for other uses. )
