Subject: [musl] [PATCH 1/1] honor __WCHAR_TYPE__ on x86_64, arm, arm64, riscv64
Date: Tue, 11 Jan 2022 01:25:18 +0100	[thread overview]
Message-ID: <20220111002518.178068-1-heinrich.schuchardt@canonical.com> (raw)

Some programs like U-Boot are compiled with GCC option -fshort-wchar.
In this case wchar_t must be a 16 bit type.
