The clash was not of Gnulib with itself, since the part of Gnulib that 
defines these symbols is not present in the Emacs tarball. Instead, the 
clash was between Emacs's hash_lookup and hash_string (defined in 
emacs/src/fns.c) and Gnulib's hash_lookup and hash_string (defined in 
gnulib/lib/hash.c) incorrectly exported by GnuTLS's x509 implementation, 
which is used by emacs/src/gnutls.c.
