1406 unless it's necessary.
1408 * cpplib.h (parse_marker): Removed.

1468 for each category of pending option: -D/-U, -A, -include,

1470 pending block. Use head and tail pointers so we don't ever
1471 have to reverse the lists.
1473 (cpp_start_read): Break out blocks of code to their own
1474 functions: install_predefs and initialize_dependency_output.
1475 Use path_include for C_INCLUDE_PATH and friends as well as
1476 CPATH. Remove include_defaults gunk. Warn about the
1477 combination of -lang-chill and -trigraphs. Optimize string
1478 bashing. Walk each pending list once, deallocating as we go.
1480 (append_include_chain): Brought over from cppfiles.c. Mark
1481 dirs as system include dirs if and only if appending to
1482 system include path. If opts->verbose, print a notice when a
1483 dir is dropped from the include path because it doesn't
1484 exist. Fix memory leak: this function is not supposed to copy
1487 (nreverse_pending, push_pending): Removed.

7158 The strategy we now use is to pre allocate the top_elt along
7159 with the EH context so that each thread has its own top_elt.
