Could this error be reduced to a warning?

C99 7.12 (<math.h>) says:

So I guess an "#ifdef INFINITY" should be added.
This macro was introduced in C99 (as was strtod("INF")), so we still
need a fallback. And if we don't want to hack the IEEE float bit
pattern, the only choices are overflow or "1.0/0.0".
