Usually C++ facade around some C library make its usage more simple and
safe. Less lines of code to write.

Because e.g. we can hide in c++ constructor/destructor issues of correct
init/destroy.  

And yes, we must be able as in C-parser, so in C++ parser "convert"
last_err_code into real c++ exception to throw it through the rest part of
application.

As I know ANTLR3 internally do not use exceptions to do job, and this is
good. Btw, have not see yet how this was made, but I have see nice solution
in the IBM ICU library on this.
