2117 * cpplib.c: \r (one character) indicates backslash
2118 newline, not \\\n (two characters). It cannot appear in the

2145 formatting. Remove stale code.
2146 (cpp_get_token): Break out string parsing code to
2147 parse_string. Use skip_comment for CHILL comments too. Use
2148 copy_comment for put_out_comments instead of dinking with
2149 marks. Remove stale code. Don't call output_line_command
2150 unless it's necessary.
2152 * cpplib.h (parse_marker): Removed.
2153 (struct cpp_buffer): Line_base is now a unsigned char *; add

2218 functions: install_predefs and initialize_dependency_output.
2219 Use path_include for C_INCLUDE_PATH and friends as well as

2221 combination of -lang-chill and -trigraphs. Optimize string
2222 bashing. Walk each pending list once, deallocating as we go.
2224 (append_include_chain): Brought over from cppfiles.c. Mark
2225 dirs as system include dirs if and only if appending to
2226 system include path. If opts->verbose, print a notice when a
2227 dir is dropped from the include path because it doesn't
2228 exist. Fix memory leak: this function is not supposed to copy

2247 fp->system_header_p.
2248 (actual_directory): Set x->sysp from
2249 CPP_BUFFER (pfile)->system_header_p so that one system header
2250 may include another with "".

2252 cause all dependencies after the first two lines to be lost.
2254 * cpplib.c (cpp_unassert): New function.

7787 out the definition. It was being called incorrectly and at
7788 the wrong times. Until a VMSie can look at this, it's better

7900 The strategy we now use is to pre allocate the top_elt along
7901 with the EH context so that each thread has its own top_elt.
7902 This is necessary as the dynamic cleanup chain is used on the
7903 top element of the stack and each thread MUST have its own.
