Sorry- scratch that. My output now looks like:

gcc -Wall -Wformat-security -Wno-format-zero-length  -g -O3 -I. 
-I/usr/include -I/usr/local/include  -DLIBDIR='"/lib/l2tpns"'

-DHAVE_EPOLL -DBGP -c -o arp.o arp.c

I'll try and work it out on my own, but if anyone wants to chip it'd be 
very welcome. Sorry for the cruft :)
