3513
        Instead of using 0 to represent the working directory, and ""
3514
        to represent a directory to be ignored, use "" for the former,
3515
        and assume the latter has been removed before we get here.

3532
        Move filename mapping into new remap_include_file function.
3533
        First try to find file by name in include_hashtab;
3534
        if that doesn't work, open and fstat it and try to find it
3535
        by inode and dev in include_ino_hashtab.
3536
        (finclude): Get file status from inc->st instead of invoking fstat.

        Unify the 3 separate mechanisms for avoiding processing
3549
        of redundant include files: #import, #pragma once, and

9803
        enables generating more reasonable code for sne.  Add a recognizer
