There are actually 4 unused external symbols resulting from Brian's 'bc/sha-256' branch. The new unused externals in 'pu' looks like:

    $ diff nsc psc
    37a38,39
    > hex.o	- hash_to_hex
    > hex.o	- hash_to_hex_algop_r
    48a51

    72a77,78
    > sha1-file.o	- hash_algo_by_id
    > sha1-file.o	- hash_algo_by_name
    $

The symbols from hex.o and sha1-file.o being the 4 symbols from this branch.

I suspect that upcoming patches will make use of them. ;-)
