Hi Alex

Bringing the arguments up to the community may help you find solutions you 
for your problems, like this static issue. We appreciate the input, 
obviously.

It is supported and tested. However, like I explained to you in the 
private email, the reason we don't provide a binary installable package 
for Windows 64-bit is that it takes far too long to build and we have too 
many packages already.

Besides all the source packages (X11, Windows, Mac, Embedded Linux, 
Windows CE), for which there are commercial and open source editions, plus 
two source evaluation packages (X11 and Embedded Linux), we provide 
binaries for Mac (32-bit PPC and x86) in commercial, opensource and 
evaluation editions, and binaries for Windows, VS2003, VS2005, VS2008 and 
MinGW, and Windows CE (VS2005). Of the Windows packages, the MinGW build 
is opensource, the rest is commercial and eval.

That's 26 packages in all produced at every package build. Even 
considering they're all built in parallel, the process takes 6 hours to 
finish. We know from experience that Windows 64-bit takes far longer to 
build, so the process would be longer.

But that's not the problem. The problem is that each and every package has 
to be tested. The platform is supported and we have automatic tests 
running to guarantee that. However, each package to be released requires 
manual testing, to ensure that it installs and works.

So the problem is actually manpower: we decided we will not release a 
package (or support a platform) unless we can do proper QA on it. I would 
actually be surprised if anyone asked us the opposite.

PS: the next package we're probably going to add is Windows CE built with 
VS 2008 and Mac 64-bit (Cocoa).
