akr ee0f448fea * util.c: parenthesize macro arguments.

naruse c383fbf93f * util.c (ruby_strtod): this code uses FPU's rounding system. 
But x86's FPU calculates double precision floating-point
  numbers in 80bit precision, so it fails to round the value.
  So ensure the value is assigned a variable. [ruby-dev:42551]
