    TYPE REPRESENTING A FILE NAME

    The filename structure is used to represent a tcc input or output
    file.  It has an associated name (the full pathname), a basename
    (with the directory and file suffix removed), a file type (see
    below) and a file storage type (see below).  filenames are formed
    into lists using the next field.  The may also be associated into
    groups which are passed around as if they were a single file using
    the aux field.

    may also contain input options which are treated like input files
    (for example, system libraries).  The second type includes the
    preserved intermediate files.  In fact PRESERVED_FILE is only used
    as the input to make_filename.
