Subject: [PATCH] Remove -Wall -Werror from the default CFLAGS. Add --with-warn
option to configure, making it easy to select between a couple of predefined
warning options.
Having all warnings on and treated as errors wasn't so good,
since different versions of gcc have different warnings.
There's no need to make it harder than it should be to build
btpd.
