gcc.c (default_compilers, cpp-output): Pass -fpreprocessed.
* gcc.c (default_compilers, cpp-output): Pass -fpreprocessed.
* toplev.c (documented_lang_options): Add -fpreprocessed.
* cpplib.h (struct cpp_buffer): Add preprocessed.
* cppinit.c (cpp_handle_option): Handle -fpreprocessed.
(cpp_start_read): Don't expand macros or emit an initial #line
directive if -fpreprocessed.
* cpplib.h (struct cpp_buffer): Added manual_pop for
better C++ tokenization.
* cpplib.c (cpp_get_token): Return CPP_EOF if manual_pop.
Also, support C++ tokenization for ->*, .*, <?, and >? operators.
* c-common.c (cpp_token): Make non-static.
