Yes. The code generator is intertwined with the parser. Also, I seem to 
remember reading somewhere that a single pass C++ compiler is impossible 
due to the nature of the language. tcc is a single pass compiler.

Perhaps you could put a C++-to-C compiler in front of tcc. Such code can 
still be found on the net. IIRC the very first C++ implementation was done 
like that (cfront plus a normal C-compiler). Later on, certain 
C++ "features" were nearly impossible to translate and they moved on to a 
dedicated C++ compiler. Perhaps "they" have overcome these problems because 
LLVM is able to generate C from C++.
