24 * FreeBSD's libc has three symbols for every symbol:
25 *
26 *     __f will be the actual implementation.
27 *     _f will be a weak reference to __f (used for calls to f from within the library).
28 *     f will be a weak reference to __f (used for calls to f from outside the library).
29 *
30 * We collapse this into just the one symbol, f.
