You must be unfamiliar with how backporting is handled in Ruby.  If the issue doesn't exist in the master branch but needs backporting, the issue is closed and the appropriate backport flag is set.  The branch maintainer will use a view like https://bugs.ruby-lang.org/projects/ruby-master/issues?query_id=171 to determine which tickets need backporting (note that it includes issues marked Closed, including this ticket).

vm.c:2295:9: error: implicit declaration of function 'rb_native_mutex_destroy' is invalid in C99 
```

There is also a warning below that might be worth solving:
```
vm.c:2489:34: warning: expression does not compute the number of elements in this array; element type is 'const int', not 'VALUE' (aka 'unsigned long') [-Wsizeof-array-div]
                             sizeof(ec->machine.regs) / sizeof(VALUE));
                                    ~~~~~~~~~~~~~~~~  ^
vm.c:2489:34: note: place parentheses around the 'sizeof(VALUE)' expression to silence this warning
```
