from the code:

                /* The following array declarations and backreferenced
                #defines is one way to fake Forth's
                        VARIABLE <name> <number> ALLOT
                in C.                                           */

    byte    path[TOKENSIZE], perms[TOKENSIZE], capes[TOKENSIZE],
            owner[TOKENSIZE], size[TOKENSIZE], spam[TOKENSIZE];

    byte  buffer[READSIZE];

    #define path    (int) & path
    #define perms   (int) & perms
    #define capes   (int) & capes
    #define owner   (int) & owner
    #define size    (int) & size
    #define spam    (int) & spam
    #define buffer  (int) & buffer

this code casts a pointer to an integer -- never do this.  just
how portable will the cast be?  take the alpha for example:  it
has 32 bit ints and 64 bit pointers IIRC.
