These values are only correct for 64-bit double, not 80-bit long double.
The compiler is completely unprepared for you to do

#define __glibcpp_long_double_bits __glibcpp_double_bits

without doing

#define LONG_DOUBLE_TYPE_SIZE 64

I.e. you've got a mismatch here in your definition of long double.
Address that (one way or the other) and things will work.
