Control-p and Control-n are what you're looking for.

At some point C type names became actual words, are are found in the
alien.c-types vocabulary.
Note that if you have both 'math' and 'alien.c-types' in your using
list, you'll get an error if you refer to 'float' since both vocabs
define such a word. So usually what we do is
QUALIFIED-WITH: alien.c-types c
And then refer to C types with a c: prefix, eg c:float, c:void*, and so on.
