When compiling ruby trunk, I get a warning on bigdecimal.c:

compiling bigdecimal.c
bigdecimal.c:3699:1: warning: ‘Zero’ defined but not used [-Wunused-function]
 Zero(void)
 ^~~~

I had a quick look at the code. I indeed did find zero uses of the Zero function. I found one use of a similar One function. (Maybe that parallel is the point? :-)

I think the warning can easily be used by removing the Zero function and the constant it uses, or by using the Zero function once. But I didn't want to make a change in a part of the code that I don't really know.
