X10 7 2

Hi,

These are some accumulated small patches we've been maintaining as part of the X10 project (http://http://x10-lang.org/).  It would be great if we could get some/all of these merged back into the mainline.  They enable BDWGC to be used on a variety of HPC Systems (IBM BlueGene/P and BlueGene/Q, Fujitsu's FX10, and on Power/Linux systems with IBM Parallel Environment).

I'd be happy to discuss them with you if things are unclear or there are better ways to accomplish.

thanks,
