>Description:

	As proposed on tech-userlevel:

	> I propose to enable -ftrivial-auto-var-init for all libraries
	> and utilities in userland by default (under gcc and clang),
	> and specifically to zero-initialize local variables in
	> release builds and to nonzero-initialize them in current
	> builds.

	https://mail-index.netbsd.org/tech-kern/2026/07/20/msg031158.html

	This issue is to track enabling it in all libraries and
	binaries that NetBSD ships -- but not enabling it in the
	toolchain by default for user programs, or in pkgsrc; we can
	consider those separately.
