Charm++ parallel programming system

Hi,

I was checking your Charm++ implementation of the Barnes-Hut method on examples/charm++/barnes-charm.

I was having the following error when trying to compile with the command "make"

make

../../../multicore-linux64/bin/charmc -g -O3  -c TreePiece.cpp

In file included from TreePiece.cpp:1:0:

barnes.h:260:72: error: conflicting declaration ‘CkArrayIndex1D parent’

barnes.h:260:22: error: ‘parent’ has a previous declaration as ‘CmiUInt8 parent’

I came with the following fix:

I hope you can use it in the next commit :)
