Re: Build failure on FreeBSD/PowerPC 32-bit

SB-IMPL::EXPECTED-N-EMPTY-BUCKETS calls EXP, that's probably where it
picks up a NAN or something.

I'm slightly confused why UNARY-TRUNCATE-SINGLE-FLOAT-TO-BIGNUM is trying to signal a type error about an object the name of whose type is a list.  Also, if I purposely call unary-truncate-single-float-to-bignum with unbound-marker, then I get a fairly hard crash (which is reasonable since it is system-internal), and not a type error.
