From 967cce191f50090d5cbd3841ee2bbb7835afeae2 Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Mon, 7 Feb 2022 17:23:15 +0100 Subject: [PATCH] tools/nolibc/std: move the standard type definitions to std.h The ordering of includes and definitions for now is a bit of a mess, as for example asm/signal.h is included after int definitions, but plenty of structures are defined later as they rely on other includes. Let's move the standard type definitions to a dedicated file that is included first. We also move NULL there. This way all other includes are aware of it, and we can bring asm/signal.h back to the top of the file. Signed-off-by: Willy Tarreau Signed-off-by: Paul E.
