I built cairo as follows:

    ./configure --build=i686-w64-mingw32 --disable-xlib --disable-xcb
    make
    make install

configure reported the following:

The following font backends:
   User:          yes (always builtin)
   FreeType:      yes
   Fontconfig:    yes
   Win32:         yes
   Quartz:        no (requires CoreGraphics framework)

I built pango as follows:

    ./configure --build=i686-w64-mingw32 --with-included_modules
    make
    make install

When building my application I used:

`pkg-config --cflags --libs glib-2.0 pangocairo`

I don't know about ClearType.  How is that enabled/disabled?
