Some of the structures, notably 'cmd', in the lib console stuff are a little too generically named and have collided with some other code so prefix the names a bit more cleanly with console_ The change is largely mechanical, and folks with out of tree code can easily switch by renaming: cmd -> console_cmd cmd_args -> console_cmd_args cmd_block -> console_cmd_block console_cmd -> console_cmd_func Apologies if this breaks you but it should be pretty easy to fix.
