v1.1.0 build failure on NetBSD

[0323pin]

Using Rust-1.91.1 on NetBSD-dev branch I get the following mismatched types when building mio v1.1.0
as a dependency of nostui, see akiomik/nostui#180

Any pointers on how to fix this?
Thanks

#1923 had a fix.
The root cause is libc 0.2.178 made some breaking changes for NetBSD.

Note that there were a large number of fixes on NetBSD for this libc release, some of which include minor breakage.

Thank you for your fix and for your reply.

I was aware of the changes in libc but didn't think of it. I'd guess I need to wait for an update. Until then, just crossing my fingers that the combination of versions of libc and mio that causes this doesn't propagate too far. We have about 175 packages that depend on mio.

@AaronChen0 I'd guess we can close this as the fix has been merged. Or, would you like to keep it open until a new release is out?

[AaronChen0]

@Thomasdezeeuw Can we have a new release?

[Thomasdezeeuw]

As mentioned above this was fixed by #1923. Releasing a new version in #1925.

Thank you!
