The both prototypes listed are *exactly* the same. And both are wrong.
Looks like you're dealing with typically broken Sun compiler.
Try defining const to nothing or removing it from this prototype.
I suspect the thing is just so old and broken that it does not even
know anything of const.

Huh?! Ever heard of forward declaration?
