2967 Improve performance.
2968 (find_position): New function.
2970 * cpplib.c: \r (one character) indicates backslash
2971 newline, not \\\n (two characters). It cannot appear in the
2972 middle of a token. Call CPP_BUMP_LINE (pfile) whenever
2973 parsing moves past \n or \r. Increment pfile->lineno whenever
2974 a \n is placed into token_buffer. Only one mark can exist at

2998 formatting. Remove stale code.
2999 (cpp_get_token): Break out string parsing code to
3000 parse_string. Use skip_comment for CHILL comments too. Use
3001 copy_comment for put_out_comments instead of dinking with
3002 marks. Remove stale code. Don't call output_line_command
3003 unless it's necessary.
3005 * cpplib.h (parse_marker): Removed.
3006 (struct cpp_buffer): Line_base is now a unsigned char *; add
3007 `mark' [long], remove `marks' [struct parse_marker *].

3071 functions: install_predefs and initialize_dependency_output.
3072 Use path_include for C_INCLUDE_PATH and friends as well as

3074 combination of -lang-chill and -trigraphs. Optimize string
3075 bashing. Walk each pending list once, deallocating as we go.
3077 (append_include_chain): Brought over from cppfiles.c. Mark
3078 dirs as system include dirs if and only if appending to
3079 system include path. If opts->verbose, print a notice when a
3080 dir is dropped from the include path because it doesn't
3081 exist. Fix memory leak: this function is not supposed to copy
3084 (nreverse_pending, push_pending): Removed.
3085 (APPEND): New macro for adding to pending lists.
3086 (path_include): Can now add to any partial include path.

3100 fp->system_header_p.
3101 (actual_directory): Set x->sysp from
3102 CPP_BUFFER (pfile)->system_header_p so that one system header
3103 may include another with "".

3105 cause all dependencies after the first two lines to be lost.
3107 * cpplib.c (cpp_unassert): New function.
