This is hardcoded in system.d:

OS os = OS.WindowsNT;

Wouldn't run-time detection be more useful? Considering these definitions:

enum OS
{
Windows95 = 1,
Windows98,
WindowsNT,
Windows2000,

RedHatLinux,
}

Trying to do this myself, my program failed to compile using
OSVERSIONINFO and GetVersionEx. Any Windows library I can link in?

std.c.windows.windows is missing quite a chunk of the Win32 API definitions. Whenever something from Windows is undefined, all you need do is look in the Windows headers for your C compiler and use that to define them in your D module. Or am I missing something?

Do you mean with copy+paste? Well, that might work. (Haven't tested it yet, though.) Can we expect any legal problems from Microsoft? ;-) Mathias

The MSDN documentation is fair game I think. And it has callign conventions in it. Not as fast as copy+paste, but it's something. Sean
