[XeTeX] The arcs package

Hi Everyone,

A couple of years ago, I raised an issue I had encountered with the arcs
package (see below for the complete run of messages). A solution was
proposed by Michael Sharpe and Joseph Wright wrote that he would mention
the issue on c.t.t., as messages to arcs' author bounced. The solution,
which I add manually to arcs.sty is:

"The arcs package depends on the relsize package which did change a few
months ago in a way that requires a small change in the arcs package. You
need to add the line (just after \RequirePackage{relsize} is a good place}

\long\def \@gobblethree #1#2#3{}

and then change the line

\let \rs at size@warning = \@gobbletwo


\let \rs at size@warning = \@gobblethree

because, in relsize.sty, the macro \rs at size@warning is now defined to have
three arguments, the last of which (6.0pt) was being left as printable
text. This problem is a LaTeX issue and has nothing particular to XeTeX."

The arcs package was never updated and the issue persists. Is there anyway
these changes could be incorporated into arcs.sty? I use arcs quite often
and it would be a great help if the changes could become part of the code.

Many thanks and best wishes,
