[Qemu-devel] [PATCH 1/2] slirp: clean up conflicts with system headers


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH 1/2] slirp: clean up conflicts with system headers
Date: Thu, 22 Mar 2012 01:02:51 +0100

Right now, slirp/slirp.h cannot include some system headers and,
indirectly, qemu_socket.h.  Clean this up, and remove a duplicate
prototype that was introduced because of that.
