Should it really be zero? It should definitely be lower
Dear Mr. Laskey,
This change broke the LLVM build on OpenBSD. Would it be possible to
use FLT_MAX instead of HUGE_VALF? FLT_MAX from float.h looks more portable.

John,Both are defined on Darwin, FLT_MAX in float.h and HUGE_VALF in math.h. However, neither header seems to be based on a BSD header. I choose HUGE_VALF because it was also defined in the LINUX and FREEBSD math.h headers (seemed like confirmation to me.) I'll wait for Chris to make the call.
