Well, I haven't tested it thoroughly, so maybe there are some situations
where it doesn't work... 8-(

I'm running GenToo, and since it's optional to include bcmath, and I
didn't see any need for it, I didn't include it.
It may be the case that other Linux distros always include it in their
versions of PHP; I do not know.

If I end up having problems, I'll just have to re-install PHP with
bcmath turned on, so it's not insurmountable.
 
Oh, I've also run into something puzzling, a line which I changed...

 $FmtPV["$$hg"] = "'" . $gg . "'";

Wouldn't that work better as the following?

 $FmtPV['$' . $hg] = "'" . $gg . "'";

I'm not sure that the $$ will give what is needed.  Or maybe I'm just
being paranoid.

Yay!
