        !          4344:        * fixproto:  Re-write.  We now assume that there are two

        !          4348:        /usr/include) we only process the standard ANSI/Posix ones where
        !          4349:        we might be able to add missing prototypes.

        !          4358:        buffer (rather than reading it with stdio).  This should be more
        !          4359:        efficient, partly because we can re-write it in place.
        !          4360:        (inf_skip_spaces, inf_read_upto, inf_scan_ident):  New functions,
        !          4361:        based on skip_spaces, read_upto, and scan_ident in scan.c, but
        !          4362:        these read from the in-memory buffer mentioned above.
        !          4363:        * scan-types.sh:  Don't check for sigset_t, since it can be a
        !          4364:        struct, whose name cannot be simplify replaced by its definition.
        !          4365:        * Makefile.in (deduced.h):  Don't pass -nostdinc.

        !          9523:        Class scoping (and type value caching) redone.  The new behaviour
        !          9524:        is triggered by NEW_CLASS_SCOPING being defined to 1.  The old
        !          9525:        behavior is accomplished by defining it to the value 0.  The entries

        !          9548:        (pushtag): Don't call set_identifier_type_value.  Leave out

        !          9554:        (push_class_level_binding): New function whose guts came from
        !          9555:        pushdecl_class_level.

        !          9571:        dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots.
