do not use INFINITY (or NAN while at it..) macro
With MSVC werror bails out, that generates
warning C4756: overflow in constant arithmetic
because aparently there is
#define _HUGE_ENUF 1e+300 /* _HUGE_ENUF*_HUGE_ENUF must overflow */
#define INFINITY ((float)(_HUGE_ENUF * _HUGE_ENUF)) /* causes warning
C4756: overflow in constant arithmetic (by design) */
Great stuff..
