Subject: [PATCH 1/4] tools/nolibc: add stdint.h
Date: Sat, 4 Mar 2023 15:26:03 +0100 [thread overview]
Message-ID: <20230304142606.5995-2-w@1wt.eu> (raw)
In-Reply-To: <20230304142606.5995-1-w@1wt.eu>
From: Vincent Dagonneau <v@vda.io>
Nolibc works fine for small and limited program however most program
expect integer types to be defined in stdint.h rather than std.h.
This is a quick fix that moves the existing integer definitions in std.h
to stdint.h.
