I think your problem lies with your use of the word 'struct':

Probably, changing the cast to (filenode *) will be all that is necessary.
This is because now that you have defined 'filenode' as a TYPE you don't
need to use the 'struct' to identify it as a struct.

This may still cause problems (as 'filenode *' may be regarded as a different
type from 'struct filenode *' and thus give an implicit cast error/warning)

For such recursive definitions, I typically use something like:

typedef struct _bob
{
  _bob *thingo;    /* or possibly 'struct _bob *' ... my memory is dim */
} bob;

... it defines a struct type _bob that you can use in the declaration but
afterwards you use 'bob' everywhere (i.e. bob *mypointer). This should
work fine.
