Subject: [PATCH 6/6] fix -dD for never-defined #undef
Date: Tue, 4 Apr 2017 23:49:55 +0200 [thread overview]
Message-ID: <20170404214955.47926-7-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20170404214955.47926-1-luc.vanoostenryck@gmail.com>
Note: to support this, we have to create a symbol where
it wasn't needed before.
