— Safer way to create the global mutex.
__attribute__((constructor)) might not have been called when the runtime
is first used. However, the first usage of the runtime is always
single-threaded, so it is safe to do it this way. (user: js, size: 1906) [annotate] [blame] [check-ins using] [more...]

— Rename ERROR() to OBJC_ERROR().
ERROR seems to be defined on MinGW32 and it's likely that it's also used
on other systems, thus it's better to prefix it with OBJC_. (user: js, size: 1926) [annotate] [blame] [check-ins using]
