MinGW-w64 - for 32 and 64 bit Windows News

With apologies to those that like to track our latest and greatest revision (which is usually very stable), we are in the middle of a giant upgrade to be announced next week. So, there is a lot of churn, and as a result, please do not use any version of trunk greater than r3197 until the new announcement next week.

Thanks for all of your support!
