From cbe5cdfcd31633edce4ee78ebc008b922de571e3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 10 Nov 2013 10:26:48 -0700 Subject: [PATCH] sandbox: Use system headers first for sandbox's os.c This file must be compiled with system headers, even if U-Boot has headers of the same name. The existing solution for this is good enough for libfdt, but fails when we have headers like stdint.h in U-Boot. Use -idirafter instead of -I, and remove the -nostdinc and other things that we don't want for this file. The best way to do this is to keep a copy of the original flags, rather than trying to filter them later.
