1.03 Mon 22 Nov 2010
	- No CPAN Testers failures, moving to production release

1.02_01 Thu 16 Sep 2010
	- Trying for a much more advanced can_xs() alternative to can_cc()
	  to deal with the situation where a host has a superficially
	  working compiler, but completely screwed up headers.
	- Adding some fallback strategies to deal with cases where these
	  same machines don't support configure_requires.
	- Adopt Chorny's eumm-upgrade style for the Makefile.PL.
	- Allow the Makefile.PL to build it's own META.yml now.
