Completed function declarations and/or added prototypes.

Staticized some functions.

__purified some functions.  Some functions were bogusly declared as
returning `const'.  This hasn't done anything since gcc-2.5.  For
later versions of gcc, the equivalent is __attribute__((const)) at
the end of function declarations.
