+ 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.
+ A derived pretty-printer can override any function listed in the
+ vtable below. See cp/cxx-pretty-print.h and cp/cxx-pretty-print.c
