No, the configure results on wrasse look pretty ordinary:
checking size of void *... 8
checking size of size_t... 8
checking size of long... 8
checking alignment of short... 2
checking alignment of int... 4
checking alignment of long... 8
checking alignment of double... 8
I wondered for a moment about force_parallel_mode, but wrasse doesn't
appear to be setting that, and in any case I'm pretty sure it only
affects plannable statements.
