07:52 AM Ruby Feature #22400: Use rb_long_t for lengths so that String and Array can exceed 2GiB on mswin

@hsbt what's the migration path for C extensions? I don't see a `HAVE_RB_LEN_T`, should we provide one so that extensions can declare:
```c
#ifndef HAVE_RB_LEN_T
typedef long rb_len_t;
typedef unsigned long rb_ulen_t;
#endif
``` byroot (Jean Boussier)

07:49 AM Ruby Feature #22400: Use rb_long_t for lengths so that String and Array can exceed 2GiB on mswin

> Were completely different names considered, such as len?
Also the natural type to go for would be `size_t`, so `rb_size_t` would make more sense than `rb_long_t`? But then there's the sign difference... byroot (Jean Boussier)

04:13 PM Ruby Bug #22406: Process.fork can leave the child unable to resolve hostnames: getaddrinfo helper threads take glibc's resolver lock after releasing the fork lock
