    Description

      Moved from the Rogue Wave bug tracking database:

      ***Created By: sebor @ May 09, 2002 11:15:41 AM***
      The template __rw_new_capacity() uses floating point arithmetic which may be less efficient than integer arithmetic on some architectures. Need to change to integer arithmetic and correctly handle integer overflow.
