Hello,

Thank you for the review and feedback on my earlier submissions.

In the following email I am including a patch which depends on the
following patches by Evgeny Karpov <Evgeny.Karpov@microsoft.com>
and Thirumalai Nagalingam <thirumalai.nagalingam@multicorewareinc.com>
that have not yet been merged:

  [PATCH 01/28] Cygwin: Add ARM64 support for SEH handler symbol references
  [PATCH 04/28] Cygwin: Add SEH workaround for aarch64 compilation

The patches can be found in the series here:
https://cygwin.com/pipermail/cygwin-patches/2025q4/014396.html

My patch applies cleanly on top of those patches and current main as of
February 18th, 2026.

Best regards,
Igor Podgainoi
