Subject: [PATCH] Add two new warnings to warning.m4
Date: Wed, 3 Jun 2026 13:05:14 -0600 [thread overview]
Message-ID: <20260603190514.333176-1-tromey@adacore.com> (raw)
I recently learned that GCC has improved -Wdangling-reference and
added -Wunterminated-string-initialization. Both of these seem
sensible to me, so this patch adds them to warning.m4.
gdb rebuilds cleanly with this in place on x86-64 Fedora 43.
