# no-define: PACKAGE and VERSION will not be #define'd in config.h (a bunch
# of other PACKAGE_* variables will, however, and there's nothing
# we can do about that; they come from AC_INIT).
# foreign: we don't follow the normal rules for GNU packages (no COPYING
# file in the top srcdir, etc, etc), so stop complaining.
-# no-dependencies: turns off auto dependency generation (just for now)
# -Wall: turns on all automake warnings...
# -Wno-portability: ...except this one, since GNU make is required.
