Thanks! I'll check in this patch in a little bit. Meanwhile I want to
comment on a few small nits that I'll clean up before I apply it.

Per coding standards, the pointer star needs to go on the variable name.

The scalar() here is unnecessary. No big deal.

I'll change the date to 2007.

Eventually it might be better to move these variables into the parent
interpreter. For now, I don't think anyone's embedding multiple Parrots into
a single program.

I don't remember what the memory allocation characteristics are of
string_from_const_cstring(), so these functions may need comments
saying "It's your responsibility to free this string."

This looks like part of a separate patch.

The new line should come after the variable declarations, per my understanding
of C89. This is difficult to remember. Stupid C89.
Good patch!
