Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

You've hit one of the warts in Charm++, that users must define a
constructor that takes CkMigrateMessage* for all chare types, but
doesn't want it declared in the .ci file. In your test code, removing
line 26 of t3.ci eliminates the error.

I think I'll fix this by making charmxi ignore that superfluous
declaration, since it takes it for granted anyway.
