The bug complains about PA_CLAMP_VOLUME, but has that macro ever worked
in applications? If not, we could remove PA_CLAMP_VOLUME from the public
API without breaking compatibility. The required patch would be much
simpler:

-/** Clamp volume to the permitted range. \since 1.0 */
+#ifdef __INCLUDED_FROM_PULSE_AUDIO
 #define PA_CLAMP_VOLUME(v) (PA_CLAMP_UNLIKELY((v), PA_VOLUME_MUTED, PA_VOLUME_MAX))
+#endif
