directx with d

Finally I have found the time to investigate this issue.
And the winner is...

Same code will follow with phobos then with tango:

//phobos
import std.c.windows.windows;

struct CUSTOMVERTEX { FLOAT x; };
static CUSTOMVERTEX[3] vertices = [ { 150.0f } ];

void main() { printf ("%d",vertices.sizeof); }

Prints 12.

//tango
import tango.sys.win32.Types;
import tango.stdc.stdio;

struct CUSTOMVERTEX { FLOAT x; };
static CUSTOMVERTEX[3] vertices = [ { 150.0f } ];
void main() { printf ("%d",vertices.sizeof); }

Prints 24.

The difference lies:

Phobos, \dmd\src\phobos\std\c\windows\windows.d:
alias float FLOAT;

Tango, D:\D\import\tango\sys\win32\Types.di:
alias double FLOAT;

(Before you ask, I use type FLOAT - uppercase - because I copy some directx code, which already uses that.)
With directx on win32, the phobos approach is working, Tango FLOAT produces errors.

Is this intended in Tango? Is there already code requiring FLOAT to be double?

The problem in the original post is disappears (and the directx triangle appears), if I use float instead of FLOAT (so double in Tango).
