Hi, I'd still like to see this fixed. I just uploaded a new version of the patch that uses gsl_isnan, GSL_POSINF, and GSL_NEGINF instead of isnan, HUGE_VAL, and -HUGE_VAL. I don't think there is any cleaner way to solve the problem, but even if there is, it would be better to apply this patch than no patch at all.

(file #47547)

The patch uses HUGE_VAL (C99) and isnan() checks - there is probably a cleaner way to handle the problem, but will require further investigation
