A better workaround is to override /usr/include/unistd.h with your own private
copy. See below for an example that you could include into your project source
tree as 'unistd.h'.

#ifdef __block
#       undef __block
#       include_next "unistd.h"
#       define __block __attribute__((__blocks__(byref)))
#else
#       include_next "unistd.h"
#endif
