Fix:

error: incompatible function pointer types assigning to 'void (*)(PangoEngineShape *, PangoFont *, const char *, unsigned int, const PangoAnalysis *, PangoGlyphString *, const char *, unsigned int)' (aka 'void (*)(struct _PangoEngineShape *, struct _PangoFont *, const char *, unsigned int, const struct _PangoAnalysis *, struct _PangoGlyphString *, const char *, unsigned int)') from 'void (PangoEngineShape *, PangoFont *, const char *, gint, const PangoAnalysis *, PangoGlyphString *)' (aka 'void (struct _PangoEngineShape *, struct _PangoFont *, const char *, int, const struct _PangoAnalysis *, struct _PangoGlyphString *)') [-Wincompatible-function-pointer-types]
