- fpclassify() now returns FP_ZERO both for 0 and -0.

- nan() and nanf() now return quiet NaNs.

- Added internal __inf() and __inff() functions.

- strtof() now calls nanf() and __inff(), respectively, to produce
  the special floating point values for nan/inf/infinity.

- strtod() now calls nan() and __inf(), respectively, to produce
  the special floating point values for nan/inf/infinity.

- The scanf() family now calls nan() and __inf(), respectively, to
  produce the special floating point values for nan/inf/infinity.
