Subject: [musl] [PATCH] arm: Use __WCHAR_TYPE__ for wchar_t if defined
Date: Fri,  3 Feb 2023 22:30:21 -0800	[thread overview]
Message-ID: <> (raw)

When building with -fshort-wchar the definition of wchar_t is
incorrect. Get the correct definition from the compiler if available.

This is useful when reusing the freestanding parts of musl on a
bare-metal target that uses -fshort-wchar.
