5343 move it out of tokens that it appears in the middle of.
5344 Improve performance.
5345 (find_position): New function.
5347 * cpplib.c: \r (one character) indicates backslash
5348 newline, not \\\n (two characters). It cannot appear in the
5349 middle of a token. Call CPP_BUMP_LINE (pfile) whenever
5350 parsing moves past \n or \r. Increment pfile->lineno whenever
5351 a \n is placed into token_buffer. Only one mark can exist at

5375 formatting. Remove stale code.
5376 (cpp_get_token): Break out string parsing code to
5377 parse_string. Use skip_comment for CHILL comments too. Use
5378 copy_comment for put_out_comments instead of dinking with
5379 marks. Remove stale code. Don't call output_line_command
5380 unless it's necessary.
5382 * cpplib.h (parse_marker): Removed.
5383 (struct cpp_buffer): Line_base is now a unsigned char *; add
5384 `mark' [long], remove `marks' [struct parse_marker *].

5448 functions: install_predefs and initialize_dependency_output.
5449 Use path_include for C_INCLUDE_PATH and friends as well as
5450 CPATH. Remove include_defaults gunk. Warn about the
5451 combination of -lang-chill and -trigraphs. Optimize string
5452 bashing. Walk each pending list once, deallocating as we go.
5454 (append_include_chain): Brought over from cppfiles.c. Mark
5455 dirs as system include dirs if and only if appending to
5456 system include path. If opts->verbose, print a notice when a
5457 dir is dropped from the include path because it doesn't
5458 exist. Fix memory leak: this function is not supposed to copy
5461 (nreverse_pending, push_pending): Removed.
5462 (APPEND): New macro for adding to pending lists.
5463 (path_include): Can now add to any partial include path.

5477 fp->system_header_p.
5478 (actual_directory): Set x->sysp from
5479 CPP_BUFFER (pfile)->system_header_p so that one system header
5480 may include another with "".

5482 cause all dependencies after the first two lines to be lost.
5484 * cpplib.c (cpp_unassert): New function.
