PROBLEM: (BCPM2048V,QAR 71547)  (Patch ID: OSF500-081)
********

This patch fixes the defragment program to properly report on extremely
large (>4.3GB) freespace holes. Previously it would report "Free space"
percentages larger than 100% and would add these large holes to the
smallest range (<100K) instead of the largest range (>10M) where they belong.

PROBLEM: (75047, 74613) (PATCH ID: OSF500-141)
********
This patch fixes a problem in which defragment reports 
incorrect extent counts on files with a large number of
extents.
