Subject: Error in GetICMProfile() declaration

In /usr/include/w32api/wingdi.h, GetICMProfile() has its second argument
declared as a DWORD.  According to:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/icm/icm_5aed.asp

it should be declared as an LPDWORD.  Indeed, in order to call this
function correctly, I current have to do something like:

	HDC dc = GetDC( NULL );
	char path[ MAX_PATH ];
	DWORD len = sizeof path;
	GetICMProfile( dc, (DWORD)&len, path );

So this really looks like a bug in the declaration.
