This line in cairo-win32-font.c looks suspicious:

    if (scaled_font->preserve_axes || scaled_font->base.options.hint_metrics 
== CAIRO_HINT_METRICS_OFF) {
        /* For 90-degree rotations (including 0), we get the metrics
         * from the GDI in logical space, then convert back to font space
         */

Sounds like it should read instead:

    if (scaled_font->preserve_axes && scaled_font->base.options.hint_metrics 
!= CAIRO_HINT_METRICS_OFF) {
        /* For 90-degree rotations (including 0), we get the metrics
         * from the GDI in logical space, then convert back to font space
         */

Though that's only about font metrics.  The code in glyph metrics does what I 
suggest.
