I'd prefer we not do that.  This is a big change to a piece of code
that has been touchy in the past.  I think it can wait until 3.1.

I think functions like this must start with `_Jv_' or must be a static
member of some class.  This name is a namespace bug.

Although we have a shocking number of calls to printf() already, I
think we should avoid adding any more.  I'd eventually not like to
require printf at all.  printf is rather big, and if you can eliminate
its use then embedded executables can be smaller.

Also I think this particular part of the patch is probably a needless
optimization.
