 I think this is a problem tied to gcc 3.4, more than the fact that it
 happens on NetBSD/macppc.
 
 The following bit of code from pixman/src/icint.h looks especially
 suspicious WRT the error:
 
 #if __GNUC__ > 3 || (__GNUC__ =3D=3D 3 && __GNUC_MINOR__ >=3D 4)
 # if __INT_MIN__ =3D=3D 0x7fffffff
 #  define _FbOnes(mask)         __builtin_popcount(mask)
 # else
 #  define _FbOnes(mask)         __builtin_popcountl((mask) & 0xffffffff)
 # endif=20
 
 I'd like to know if disabling that code works around the issue.
