Yeah, the Debian 7 instructions don't mention the compiler options for bots, but the Debian 6 wiki article does. Debian 6 instructions agree with this link:

Unfortunately, I am not seeing the DFLAGS anywhere in the Makefile files (in zone or world source folders), and the zone folder doesn't have a Makefile.common file at all. Are these sections / files something I have to add?
