cpphash.h (struct cpp_reader): Add print_version field.
* cpphash.h (struct cpp_reader): Add print_version field.
* cppinit.c (cpp_handle_option): For -v, -version, and --version,
just set print_version and other flags as appropriate.
(cpp_post_options): Print version here if print_version is set.
* toplev.c (exit_after_options): New flag.
(independent_decode_option): Don't exit here; just set
exit_after_options.
(main): Exit after calling lang_hooks.post_options if
exit_after_options is true.
* cppinit.c (append_include_chain): Drop never-used case QUOTE.
(merge_include_chains): Adjust comment to match code.
