2041 Improve performance.
2042 (find_position): New function.
2044 * cpplib.c: \r (one character) indicates backslash
2045 newline, not \\\n (two characters). It cannot appear in the

2073 (cpp_get_token): Break out string parsing code to
2074 parse_string. Use skip_comment for CHILL comments too. Use
2075 copy_comment for put_out_comments instead of dinking with

2077 unless it's necessary.
2079 * cpplib.h (parse_marker): Removed.
2080 (struct cpp_buffer): Line_base is now a unsigned char *; add

2145 functions: install_predefs and initialize_dependency_output.
2146 Use path_include for C_INCLUDE_PATH and friends as well as

2148 combination of -lang-chill and -trigraphs. Optimize string
2149 bashing. Walk each pending list once, deallocating as we go.
2151 (append_include_chain): Brought over from cppfiles.c. Mark
2152 dirs as system include dirs if and only if appending to
2153 system include path. If opts->verbose, print a notice when a
2154 dir is dropped from the include path because it doesn't
2155 exist. Fix memory leak: this function is not supposed to copy
2158 (nreverse_pending, push_pending): Removed.
2159 (APPEND): New macro for adding to pending lists.
2160 (path_include): Can now add to any partial include path.

2174 fp->system_header_p.
2175 (actual_directory): Set x->sysp from
2176 CPP_BUFFER (pfile)->system_header_p so that one system header
2177 may include another with "".

2179 cause all dependencies after the first two lines to be lost.
