2956 move it out of tokens that it appears in the middle of.
2957 Improve performance.
2958 (find_position): New function.
2960 * cpplib.c: \r (one character) indicates backslash
2961 newline, not \\\n (two characters). It cannot appear in the
2962 middle of a token. Call CPP_BUMP_LINE (pfile) whenever
2963 parsing moves past \n or \r. Increment pfile->lineno whenever
2964 a \n is placed into token_buffer. Only one mark can exist at

2988 formatting. Remove stale code.
2989 (cpp_get_token): Break out string parsing code to
2990 parse_string. Use skip_comment for CHILL comments too. Use
2991 copy_comment for put_out_comments instead of dinking with
2992 marks. Remove stale code. Don't call output_line_command
2993 unless it's necessary.
2995 * cpplib.h (parse_marker): Removed.
2996 (struct cpp_buffer): Line_base is now a unsigned char *; add

3061 functions: install_predefs and initialize_dependency_output.
3062 Use path_include for C_INCLUDE_PATH and friends as well as

3064 combination of -lang-chill and -trigraphs. Optimize string
3065 bashing. Walk each pending list once, deallocating as we go.
3067 (append_include_chain): Brought over from cppfiles.c. Mark
3068 dirs as system include dirs if and only if appending to
3069 system include path. If opts->verbose, print a notice when a
3070 dir is dropped from the include path because it doesn't
3071 exist. Fix memory leak: this function is not supposed to copy
3074 (nreverse_pending, push_pending): Removed.
3075 (APPEND): New macro for adding to pending lists.
3076 (path_include): Can now add to any partial include path.

3090 fp->system_header_p.
3091 (actual_directory): Set x->sysp from
3092 CPP_BUFFER (pfile)->system_header_p so that one system header
3093 may include another with "".
3094 (deps_output): Fix double adjustment of deps_size which would
3095 cause all dependencies after the first two lines to be lost.
3097 * cpplib.c (cpp_unassert): New function.
