I think I've been experiencing similar trouble with evil-ruby. I thought 
it was just me and that it didn't work for some time, but now we know 
that it was introduced only recently.

	typealias 'NCURSES_SIZE_T', nil, nil, nil, 'short'
	typealias 'chtype', nil, nil, nil, 'unsigned long'
	typealias 'attr_t', nil, nil, nil, 'chtype'
	typealias 'bool', nil, nil, nil, 'int'
