Subject: [PATCH v2 2/5] tools/libfsimage: Fix PATH_MAX redefinition error
Date: Fri, 30 Apr 2021 14:28:08 +0300	[thread overview]
Message-ID: <9e323285b89717cd4cd8de7fb642e447b0dcfc4e.1619781564.git.costin.lupu@cs.pub.ro> (raw)
In-Reply-To: <cover.1619781564.git.costin.lupu@cs.pub.ro>

If PATH_MAX is already defined in the system (e.g. in /usr/include/limits.h
header) then gcc will trigger a redefinition error because of -Werror.
