The main problem are not the headers. The problems are on a binary level.

The first problem is the class structure - you need knowledge of VMT etc etc etc. 
On an assembler level, the name mangling is very different from C, it also changes 
with each version of the C++ compiler. We could have bindings for GCC 2.90, and 
with GCC 3.0 they would no longer work.

They are not compiled languages, but interpreted. All you could do from FPC is to run the interpreter.
