Subject: [PATCH 15/30] kbuild: force 16-bit wchar_t treewide
Date: Mon, 22 Nov 2021 09:47:17 +0100	[thread overview]
Message-ID: <20211122084732.2597109-16-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20211122084732.2597109-1-a.fatoum@pengutronix.de>

-fshort-wchar ensures L"" expands to code units of 16-bit each. We
already enforce this on x86, but as a small step towards ARM and
RISC-V EFI support in barebox, enable it globally. We already treat
wchar_t as 16-bit everywhere where it's used (It's typedef'ed in
<linux/nls.h> and <linux/stddef.h>.
