The 'void' is only there to satisfy -Wstrict-prototypes, which
does not allow VALUE (*)() but will allow VALUE (*)(void).

Arguments to rb_define_method() and such naturally must be
casted to VALUE (*)(void).  This is a small price for the
benefit of -Wstrict-prototypes.  Unless there is some other
way to suppress these warnings (I wasn't able to find an
appropriate pragma).
