807
        directory' include searchpath entries.
808
        (struct file_name_list): Add *alloc pointer for the sake of
809

822
        the fly for current directory "" includes, use the one that's

        duplicate code from the search_start selection logic.
825
        (cpp_reader_init): Initialize pfile->actual_dirs.
826
 
827
        Remove definition of HOST_WIDE_INT.  Change calls
828
        to cpp_parse_escape to match changes in cppexp.c (note
829
        hardcoded MASK, which is safe since this is the source
830
        character set).
831
 
832
        * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
833
        to handle wide character constants in #if directives.  The
834
        function now returns a HOST_WIDE_INT, and takes a third
835
        argument which is a binary mask for all legal values (0x00ff
836
        for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.)  Define
837
        MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK.  Change callers of
838
        cpp_parse_escape to match.  [Fixes c-torture/execute/widechar-1.c]

1529
        (hack_vms_include_specification): Remove all calls and #if 0
1530
        out the definition.  It was being called incorrectly and at
1531

1532
        to not pretend to support it.

1543
        Guts ripped out and replaced with new include_hash mechanism.
1544
        (finclude): Calling convention changed as for

1561
        Understand the four partial include chains.
1562

1563
        include_hash.
1564
        (cpp_cleanup): Free the include_hash, not the import hash and
1565
        the all_include and dont_repeat lists which no longer exist.

        When looking for a store of a value not loaded in order to call
3779
