    No namespaces because this file has to be includable from C and Objective-C.
 
    Note, this file uses many GCC extensions, but it should be compatible with
    C, Objective C, C++, and Objective C++.
 
    For non-debug builds, everything is disabled by default, except for the
    RELEASE_ASSERT family of macros.
