2994 * cpplib.c: \r (one character) indicates backslash

3027 unless it's necessary.
3029 * cpplib.h (parse_marker): Removed.

3095 functions: install_predefs and initialize_dependency_output.

3098 combination of -lang-chill and -trigraphs. Optimize string
3099 bashing. Walk each pending list once, deallocating as we go.
3101 (append_include_chain): Brought over from cppfiles.c. Mark
3102 dirs as system include dirs if and only if appending to
3103 system include path. If opts->verbose, print a notice when a
3104 dir is dropped from the include path because it doesn't
3105 exist. Fix memory leak: this function is not supposed to copy

3124 fp->system_header_p.
3125 (actual_directory): Set x->sysp from
3126 CPP_BUFFER (pfile)->system_header_p so that one system header
3127 may include another with "".
