Subject: [musl] [PATCH 2/2] add -Wtype-limits to enabled warning list
Date: Sat, 10 Jul 2021 00:25:00 -0300	[thread overview]
Message-ID: <20210710032500.9249-2-ericonr@disroot.org> (raw)
In-Reply-To: <20210710032500.9249-1-ericonr@disroot.org>

this warning catches conditionals which are never true, such as checking
if an unsigned value is smaller than zero. this leads to two warnings in
the getgr_a.c and getpw_a.c files, which assume that the underlying type
for gid_t and uid_t might still change.
