 I think I read ISO C to say that windows is wrong here.
 
 When no precision is specified ISO distinguishes
 between FLT_RADIX is a power of 2: the precision is sufficient for
 an exact representation of the value; if FLT_RADIX is not a power of 2
 the precision is enough to distinguish all possible nearby values the
 double type can represent, but trailing zeros may be ommited.
 
 And of course FLT_RADIX is 2 on all relevant architectures.
