language using C/c++ syntax can derive from this datatype and reuse
facilities provided here. It can do so by having a subobject of type
c_pretty_printer and override the macro pp_c_base to return a pointer
to that subobject. Such a pretty-printer has the responsibility to
initialize the pp_base() part, then call pp_c_pretty_printer_init
to set up the components that are specific to the C pretty-printer.

vtable below. See cp/cxx-pretty-print.h and cp/cxx-pretty-print.c
