Bumps libc from 0.2.189 to 0.2.191.

Release notes

Sourced from libc's releases.

0.2.191

Support

  • Emscripten: Support v4.0.12 to v6.0.11 (#5610)

Added

  • Apple: Add F_SETNOSIGPIPE and F_GETNOSIGPIPE (#5609)
  • Apple: add ifaliasreq and in6_aliasreq (#5557)
  • FreeBSD: Add PT_* constants (#5625)
  • Haiku: Add AI_* and NI_* constants from netdb.h (#5585)
  • Hurd: Add POSIX_SPAWN_* flags (#5578)
  • NuttX: Add AT_SYMLINK_NOFOLLOW (#5614)
  • OpenBSD: Add sensordev (#5534)
  • QuRT: Add isatty (#5618)
  • WASI: Add pthread_condattr_{get,set}clock (#5626)

Fixed

  • FreeBSD-aarch64: Fix gpregs and fpregs (#5603)

Changed

  • AIX: Restore 'c_ulong' as the type of 'statvfs.f_fsid'. (#5616)
  • Android: Make prop_info an extern type (#5561)
  • Apple: Mach API is now available on non-MacOS targets again. This should resolve some issues building ecosystem crates. (#5612), (#5636)
  • FreeBSD: Add back NOTE_PCTRLMASK with a deprecation warning (#5600)

0.2.190

There is now a single config for enabling 64-bit time_t: libc_unstable_time64. This can be set unconditionally; it opts in to 64-bit time_t on the following platforms that use 32-bit by default:

  • 32-bit Linux-GNU
  • 32-bit Linux-uClibc
  • 32-bit Linux-musl. Note that setting this flag also enables some other changes that happend in musl v1.2.
  • 32-bit Windows-GNU
  • ESP-IDF (all targets with this environment are 32-bit)

Most other 32-bit platforms are either already using 64-bit time_t, or are considered legacy and will not be gaining support from their upstream maintainers.

You can enable this using RUSTFLAGS:

RUSTFLAGS='--cfg=libc_unstable_time64' cargo ...

Note that there may still be some changes to features gated by this config option, hence "unstable"
