nmap 3.81 crash on XP with pcap 3.01a

[Matthew Oelschlaeger <boelschlaeger () carolina rr com>]

Hiya,

   Found weird crash bug in nmap 3.81 binaries and source  for windows 
with nmap 3.01a. 

   It tries to reference pcap_lib_version in wpcap.dll.  However, there 
isnt a pcap_lib_version in my wpcap.dll so it fails with
ERROR_PROC_NOT_FOUND. 

nmap.exe:
045C15F:      GetProcAddress(0x390000, "pcap_lib_version") => 0
045C168:      GetLastError() => ERROR_PROC_NOT_FOUND

Heres what i used to fix the problem. No idea if its correct though :p.

<nmapsource>/mswin32/winip/winip.c @ LINE 314, FUNCTION winip_postopt_init

//old
//printf("***WinIP***  winpcap present, dynamic linked to: %s\n", 
pcap_lib_version());
//new
printf("***WinIP***  winpcap present, dynamic linked to: %s\n", 
PacketGetVersion());
