Here's the spec of what microsoft implements:
[1] http://msdn.microsoft.com/en-us/library/a1y7w461.aspx

Exactly!

And hence the current ProcessBuilder behavior is simply broken.

I'm afraid, that has turned out to be false information. Executable 
generated by Microsoft compilers seem to use some other code, that 
follows the spec given in [1], but CommandLineToArgvW does not follow 
this specification. In fact, CommandLineToArgvW doesn't do anything 
useful. Let's forget I ever mentioned it.

Yes.

I would hope, that mingw32 and mingw64 toolchains have code that is 
compatible to [1]. At least my experience with mingw and visual studio 
executables is consistent with [1].
