Hello Cygwin list,

I’ve noticed that the Clang/LLVM stable packages in Cygwin are at version
20.1.x, while the libc++-devel, libc++1, libc++abi-devel, libc++abi1,
libunwind-devel and libunwind1 packages are still at 8.0.1. According to
the package summaries, they were last updated in 2019.

This version mismatch can present issues using modern C++ features and
makes it hard to use a complete LLVM toolchain with libc++ on Cygwin.

I searched the Cygwin mailing list archives for prior posts about updating
libc++, but I didn’t find a clear request or discussion about coordinating
libc++ versions with newer Clang.

Could you clarify if there is a plan to update libc++ to match more recent
LLVM releases, or if the recommended C++ standard library for newer and
future Clang versions on Cygwin should be libstdc++.

Thank you for your time and I'm grateful for the effort you all put into
this project.

Respectfully,
Florin Tulba
