I have  the same problem with  the file tree.h, which  I can't include
from a C++ program, even with 

extern "C" {
#include "..."
}

For now, I'm writting  most of my code in pure C,  and I have wrappers
around C++ functions  written in C. When  I want to use a  tree from a
C++ file, I just typedef it to be a void *. 

But in the long run, I think that GCC's header files should compile in
C++  :  That would  be  simpler  for code  reuse  and  linking to  C++
libraries,  and anyway, most  of the  time, when  a C  program doesn't
compile in C++, this is because it's too dirty ...
