3568 Make copy of file name, and simplify the copy.
3569 Use base_name to identify the end of fname's directory.
3570 Do not prepend dir for "..." if it matches the search list's first dir.
3571 open_include_file now subsumes redundant_include_p and lookup_import.
3572 Use bypass_slot to remember when to skip directories when including
3573 a file that has already been seen.
3574 Instead of using 0 to represent the working directory, and ""
3575 to represent a directory to be ignored, use "" for the former,
3576 and assume the latter has been removed before we get here.
3577 Assume the directory prefixes have already been simplified.

3601 by inode and dev in include_ino_hashtab.
3603 (finclude): Get file status from inc->st instead of invoking fstat.
3604 Store inc into fp->inc so that record_control_macro doesn't
3605 need to do a table lookup.
