cpplib.h (enum cpp_ttype): Add token types for all punctuators.
* cpplib.h (enum cpp_ttype): Add token types for all punctuators. Distinguish pp-numbers from valid C numbers. Give some tokens better names. Initialize from macro. (struct cpp_name, cpp_token, cpp_toklist): New data structures. Update prototypes. * cpplex.c (bump_column, expand_name_space, expand_token_space, init_token_list, cpp_output_list, _cpp_scan_line): New functions. (output_line_command): Add third argument, new line number. * cpphash.h: Update prototypes. * cppexp.c, cpphash.c, cpplib.c, scan-decls.c: Update for new token names. From-SVN: r33289
