3175 (cpp_get_token): Break out string parsing code to
3176 parse_string. Use skip_comment for CHILL comments too. Use
3177 copy_comment for put_out_comments instead of dinking with

3179 unless it's necessary.
3181 * cpplib.h (parse_marker): Removed.

3247 functions: install_predefs and initialize_dependency_output.

3253 (append_include_chain): Brought over from cppfiles.c. Mark
3254 dirs as system include dirs if and only if appending to
3255 system include path. If opts->verbose, print a notice when a

8929 The strategy we now use is to pre allocate the top_elt along
8930 with the EH context so that each thread has its own top_elt.
8931 This is necessary as the dynamic cleanup chain is used on the
8932 top element of the stack and each thread MUST have its own.
