OS X: #include <CoreFoundation/CoreFoundation.h> leads to error: unknown type name 'dispatch_block_t'

$ cat t1.c
#include <CoreFoundation/CoreFoundation.h>

$ gcc t1.c

                 from /System/Library/Frameworks/CoreFoundation.framework/Headers/CFStream.h:15,

  373 |   dispatch_block_t notification_block);
      |   ^~~~~~~~~~~~~~~~

try using clang, not gnu gcc. when I was using /usr/local/bin/gcc as a compiler, met the same issue. Turning to /usr/local/clang, fix my problem.
