 * FreeBSD's libc has three symbols for every symbol:
 *
 *     __f will be the actual implementation.
 *     _f will be a weak reference to __f (used for calls to f from within the library).
 *     f will be a weak reference to __f (used for calls to f from outside the library).
 *
 * We collapse this into just the one symbol, f.
