  Modified files:
    lib/msun/src         math.h 
  Log:
  Most libm routines depend on the rounding mode and/or set exception
  flags, so they are not pure.  Remove the __pure2 annotation from them.
  I believe that the following routines and their float and long double
  counterparts are the only ones here that can be __pure2:
  
          copysign is* fabs finite fmax fmin fpclassify ilogb nan signbit
  
  When gcc supports FENV_ACCESS, perhaps there will be a new annotation
  that allows the other functions to be considered pure when FENV_ACCESS
  is off.
