The following reply was made to PR kern/56487; it has been noted by GNATS.

From: "Jason R Thorpe" <>
Subject: PR/56487 CVS commit: src/sys/arch/aarch64/include
Date: Fri, 5 Nov 2021 15:18:18 +0000

 Module Name:	src
 Committed By:	thorpej
 Date:		Fri Nov  5 15:18:18 UTC 2021
 Modified Files:
 	src/sys/arch/aarch64/include: signal.h
 Log Message:
 Normally, to support COMPAT_NETBSD32 we need to define
 __HAVE_STRUCT_SIGCONTEXT in order to support the old
 "sigcontext" style of handlers for 32-bit binaries.
 However, we only support 32-bit EABI binaries on AArch64,
 and by happy accident (due to a libc bug introduced in
 2006), 32-bit NetBSD EABI binaries never used "sigcontext"
 style handlers.  So, we don't need to carry any of this
 baggage forward.
 This addresses the AArch64 case of PR kern/56487.
