soft-fp's quad.h does not work in the case where two unsigned long 
long words are being used but unsigned long is only 32 bits (as in MIPS64 
N32).

Patch: http://sourceware.org/ml/libc-alpha/2006-06/msg00011.html

If you'd prefer a larger patch where all such bit-fields for all floating-point
formats are changed to _FP_W_TYPE, please let me know.

Fixed.
