 * Weak Linking Note:

 *

 * Correctly linking against weak symbols relies on actually having

 * the symbol available at link time, such that dyld can create its two-level

 * weak reference.

 *

 * Since we have to support building on earlier systems where the symbols

 * are not available at all, we #define the functions to NULL (with appropriate

 * function typedefs), allowing the standard approach of checking for

 * symbol != NULL to succeed.
