Windows Header consts

[Prudence via Digitalmars-d-learn]

Windows headers contain a ton of global const's for the various 
messages. Seems like a very bad way to go about this.

Could one not simply put all these in an enum? e.g., enum WM { 
WM_CREATE = 1, etc... }?

If so, because there are so many and so many references to them, 
this can't be done easily by hand. Surely there is a way to 
automate this? But because the headers are not consistently 
written, a simple search and replace won't work well?

e.g.,

const WM_* -> add to enum WM;
else WM_* -> WM.*

because there is code like

static if (_WIN32_WINNT >= 0x500) {

	enum {
		WM_CHANGEUISTATE	=	0x0127,
		WM_UPDATEUISTATE	=	0x0128,
		WM_QUERYUISTATE		=	0x0129
	}

	// LOWORD(wParam) values in WM_*UISTATE*
	enum {
		UIS_SET			=	1,
		UIS_CLEAR		=	2,
		UIS_INITIALIZE	=	3
	}

	// HIWORD(wParam) values in WM_*UISTATE*
	enum {
		UISF_HIDEFOCUS	=	0x1,
		UISF_HIDEACCEL	=	0x2
	}

}

static if (_WIN32_WINNT >= 0x501) {

	// HIWORD(wParam) values in WM_*UISTATE*
	enum {
		UISF_ACTIVE		=	0x4
	}

}

(unless one can define partial enums or use static if in the 
enums directly(probably the case but parsing is more difficult))


I guessing one would need a D or C parser to deal with all this?
