State-Changed-By: davem
State-Changed-When: Tue Jun 25 08:34:32 2002
State-Changed-Why:
    Known bug in Sun's libc implementation of the software
    quad floating point routines.  They clobber the output
    memory before the inputs are consumed.
    
    We've installed a workaround into the GCC sources to
    deal with this and the fix will appear in 3.1.1
