Hi Richard,

  We're no longer using __glibcpp_long_double_bits in C++'s <limits>.
We're getting that info from the compiler through __LONG_DOUBLE_BIT__.

However, what would be helpful is means to know whether a floating
point type uses a hidden bit.  For a 32-bit or 64-bit wide
floating-point type, that is a non-issue.  However, practice varies
greatly for the extended floating-point types.
