woops, it's not just a 64bit pointer being treated as 32.

When you run macro F_DEPTH(file) you're actually subtracting the size of a
32bit integer, ie 4 bytes, but file is a pointer to structures like this:

struct file_struct {
    const char *dirname;    /* The dir info inside the transfer */
    time_t modtime;        /* When the item was last modified */
    uint32 len32;        /* Lowest 32 bits of the file's length */
    uint16 mode;        /* The item's type and permissions */
    uint16 flags;        /* The FLAG_* bits for this item */
    const char basename[1];    /* The basename (AKA filename) follows */

The size of file_struct is 32 bytes

So when you use the F_DEPTH macro you're subtracting 4 bytes from a pointer
that should be decremented 32 bytes at a time.... 

Still crazy.
