I blogged about it at the time: 
<http://people.planetpostgresql.org/andrew/index.php?/archives/276-Microsoft-throws-large-developer-c...; 
and here when they relented a month later: 
<http://people.planetpostgresql.org/andrew/index.php?/archives/277-Microsoft-apparently-does-the-righ...;. 
That was based on sources I considered credible at the time. But 
frankly, I'm not going to spend a lot of time digging up old references. 
If you think it's FUD then feel free, but I was and am far from alone in 
thinking it wasn't. Given the work I've put in over the years in 
supporting PostgreSQL on Windows I don't think any suggestion I have a 
bias against Microsoft has much credibility.

As for mingw64, I still use this one: 
<http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Automated%20Builds/m...;. 
The reason there isn't a later more official build is that they have 
screwed up their automated build process (which I also blogged about ;-) 
<http://adpgtech.blogspot.com/2013/01/mingw64-fail.html;). I'm going to 
try to get to the bottom of that when I get a chance. But this compiler 
works perfectly well AFAICT. It's been running on one of my buildfarm 
members quite happily for quite a while.

cheers

andrew
