This is a compiler botch fixed in ANSI C (released Jan 8) and 
in the 4.0 release of Traditional C.

As Mike discovered, the workaround is to leave off the prototype argument
names:

struct rt_functab {
       int     (*ft_prep)(struct soltab *);
       int     (*ft_shot)(struct soltab *);
};

Bug reports like this are of great value!     
Thanks for taking the time to make a small and complete example.
