Ok, would something like this work? (for cairo.c.win32)
-------------------------------
//Use Andrej Mitrovic's API from
//https://github.com/AndrejMitrovic/DWindowsProgramming/tree/master/win32
version(EXT_WIN32_BINDINGS)
{
    import win32.windef;
    import win32.wingdi;
}
else
{
    import core.sys.windows.windows;
    pragma(msg, "cairo.c.win32: LOGFONTW should move to druntime");
    enum size_t LF_FACESIZE = 32;
    struct LOGFONTW
    {
        LONG lfHeight;
        LONG lfWidth;
        LONG lfEscapement;
        LONG lfOrientation;
        LONG lfWeight;
        BYTE lfItalic;
        BYTE lfUnderline;
        BYTE lfStrikeOut;
        BYTE lfCharSet;
        BYTE lfOutPrecision;
        BYTE lfClipPrecision;
        BYTE lfQuality;
        BYTE lfPitchAndFamily;
        WCHAR[LF_FACESIZE] lfFaceName;
    }
}
-------------------------------
I guess win32.windef and win32.wingdi contain all needed types?

Regarding the LGPL clause in the bindings, that's a leftover from the
cairo c headers. Even if that counted as releasing the sources as LGPL I
could still relicense them as long as I'm the only contributor. I'll
just ask on the cairo mailing list, that seems to be the best solution.
