+**  Dummy symbol to prevent an empty library.

+**  Written by Russ Allbery <rra@stanford.edu>
+**  This work is hereby placed in the public domain by its author.
+**
+**  On platforms that already have all of the functions that libportable would
+**  supply, Automake builds an empty library and then calls ar with
+**  nonsensical arguments.  Ensure that libportable always contains at least
+**  one symbol.
