    GCC versions 4.0 and higher support 128-bit quad precision
    floating point values. The XL compilers now provide the
    -qfloat=gcclongdouble option to be compatible with GCC's
    representation of 128-bit quad precision floating point
    values.

Anyone knows how to enable it?

By default, I just get the double-double representation (yielding
106-bit precision).
