3163 unless it's necessary.

3237 (append_include_chain): Brought over from cppfiles.c. Mark
3238 dirs as system include dirs if and only if appending to
3239 system include path. If opts->verbose, print a notice when a
3240 dir is dropped from the include path because it doesn't
3241 exist. Fix memory leak: this function is not supposed to copy

8913 The strategy we now use is to pre allocate the top_elt along
8914 with the EH context so that each thread has its own top_elt.
