@paleolimbot Any idea why these may fail?

Hmm...it's probably becuase PPC is big-endian? I should explicitly specify the endian flag in geos_write_wkb() when using it to test equality.

[barracuda156]

@paleolimbot Yes, ppc here (and usually) is Big-endian. (Specifically, ppc and ppc64 are Big-endian, while ppc64le is LE.)
