Problem Scanning local subnet range with -P0 option for version 3.90

["Jim Carras" <JFCECL () engr psu edu>]

   I have just upgraded to the latest version of nmap for windows
(3.90).  A command that worked with 3.81 does not work with 3.90.  The
command scans the local subnet using a range of hosts and the -P0
option.  The range specification with -P0 causes a nmap failure.  A
single local host machine can be scanned with -P0, as can a range of
machines for a subnet other than the local subnet of the scanning
system.

Ex. 
   Local scanning system has address 196.186.110.200 bitmask /24

   nmap -sV -p 22 -P0 196.168.110.10-11         -- fails with message
below

   nmap -sV -p 22 196.186.110.10-11             -- works


   MS Application Event Log entry for failure:

   0048: 65 39 63 65 0d 0a         e9ce..  

   The size of the range does not matter, only the use of -P0 with the
range.
 
   The scanning system is running fully patched XP Professional Version
2002 Service Pack 2 and WinPcap 3.1beta4.  The command functions
properly with nmap 3.81.

   Thank you for your assistance.
