             Bug #: 14103
           Summary: sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c should use

            Status: NEW
          Severity: normal

    Classification: Unclassified


sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c can be used
on target with native 64bit integer support, but 32bit
long.  It should use __builtin_clzll instead of __builtin_clzl
on int64.  A patch is posted at
