Component:  ports       |    Version:  2.8.1
 Keywords:  highsierra  |       Port:  blink
------------------------+-------------------------
 On High Sierra and earlier (actually `{clang >= 700 < 1001}` as far as I
 know):

 {{{
 ./blink/jit.h:270:10: error: address argument to atomic operation must be
 a pointer to non-const _Atomic type ('const _Atomic(bool) *' invalid)
   return atomic_load_explicit(&jit->disabled, memory_order_acquire);
          ^                    ~~~~~~~~~~~~~~
 }}}

 See https://github.com/php/php-src/issues/8881 for some background. It
 seems that there was a mistake in the original version of the C11 standard
 (something that should have been `const` was defined to be non-`const`),
 which clang obeyed, and which was changed in later versions of the
 standard; this code appears to be written to the revised C11 standard.

 To address that PHP issue, the `const`-ness is casted away like this:

 A similar patch could be written for blink.
