+When --disable-music-ogg-shared the OGG tests fail when they should pass.
+Attached is a crude patch that gets them working (though the changes done to
+configure.in, inside AC_CHECK_LIB, will produce ugly status string such as
+"checking for ov_open_callbacks in -lvorbisidec -logg", which is mostly a
+aesthetic concern)
