Building --disable-verbose-mode --disable-asserts --disable-tests cuts the library from 112K to 45K or so * configure.in: check for varargs macro support, add --enable-verbose-mode, --enable-asserts. * dbus/dbus-internals.h (_dbus_assert): support DBUS_DISABLE_ASSERT (_dbus_verbose): support DBUS_ENABLE_VERBOSE_MODE
