Hi Orjan,

I proofread this and tested it on a Red Hat 7 Linux native system.
It works for me.

ISO C standard section 5.2.4.2, "numerical limits", addresses this.
It says: "minimum normalized positive floating-point number:"

  FLT_MIN  1e-37
  DBL_MIN  1e-37
  LDBL_MIN 1e-37

So I agree; it is legal for an implementation to implement
doubles as 32-bit IEEE 754 numbers.

I recommend this patch for approval but I do not have approval power.
Fernando?  Stan?
