Funny.  real.mant_dig == 106 means 128bit IBM long double (or as some call it,
double-double as the error message suggest).  

The error message is incorrect in both cases too:
"Only 64-bit, 80-bit, and 128-bit reals"~
      " are supported for LittleEndian CPUs"

Should really be:
"Only IEEE 64-bit, IEEE 80-bit, and IEEE 128-bit reals"~
      " are supported for LittleEndian CPUs"

And:
"Only IEEE 64-bit and IEEE 128-bit reals are supported for BigEndian CPUs."~
    " double-double reals have partial support"
