With this update, you can now always use the`core::ffi::c_*` types with `libc` definitions, since `libc` has been changed to reexport from`core` rather than redefining them.

Setting the`MUSL_V1_2_3` variable also enables some newer API unrelated to `time_t`.### Added- L4Re: Add uclibc aarch64 support ([#4479](https://github.com/rust-lang/libc/pull/4479))- Linux, Android: Add a generic definition for `XCASE` ([#4847](https://github.com/rust-lang/libc/pull/4847))- Linux-like: Add `NAME_MAX` ([#4888](https://github.com/rust-lang/libc/pull/4888))- Linux: Add `AT_EXECVE_CHECK` ([#4422](https://github.com/rust-lang/libc/pull/4422))- Linux: Add the `SUN_LEN` macro ([#4269](https://github.com/rust-lang/libc/pull/4269))- Linux: add `getitimer` and `setitimer` ([#4890](https://github.com/rust-lang/libc/pull/4890))- Linux: add `pthread_tryjoin_n` and `pthread_timedjoin_np` ([#4887](https://github.com/rust-lang/libc/pull/4887))- Musl: Add unstable support for 64-bit `time_t` on 32-bit platforms ([#4463](https://github.com/rust-lang/libc/pull/4463))- NetBSD, OpenBSD: Add interface `LINK_STATE_*` definitions from `sys/net/if.h` ([#4751](https://github.com/rust-lang/libc/pull/4751))- QuRT: Add support for Qualcomm QuRT ([#4845](https://github.com/rust-lang/libc/pull/4845))- Types: Add Padding<T>::uninit() ([#4862](https://github.com/rust-lang/libc/pull/4862))### Fixed- Glibc: Link old version of `cf{g,s}et{i,o}speed` ([#4882](https://github.com/rust-lang/libc/pull/4882))- L4Re: Fixes for `pthread` ([#4479](https://github.com/rust-lang/libc/pull/4479))- L4re: Fix a wide variety of incorrect definitions ([#4479](https://github.com/rust-lang/libc/pull/4479))- Musl: Fix the value of `CPU_SETSIZE` on musl 1.2+ ([#4865](https://github.com/rust-lang/libc/pull/4865))- Musl: RISC-V: fix public padding fields in `stat/stat64` ([#4463](https://github.com/rust-lang/libc/pull/4463))- Musl: s390x: Fix definition of `SIGSTKSZ`/`MINSIGSTKSZ` ([#4884](https://github.com/rust-lang/libc/pull/4884))- NetBSD: Arm: Fix `PT_{GET,SET}FPREGS`, `_REG_TIPDR`, and `_REG_{LR,SP}` ([#4899](https://github.com/rust-lang/libc/pull/4899))- NetBSD: Fix `if_msghdr` alignment ([#4902](https://github.com/rust-lang/libc/pull/4902))- NetBSD: Fix `siginfo_t` layout on 32-bit platforms ([#4904](https://github.com/rust-lang/libc/pull/4904))- NetBSD: change definition of `pthread_spin_t` to allow arch redefinition.
