Wireshark-dev: [Wireshark-dev] Compiling Wireshark for Win32

Hello,

I am a bit surprised about a problem with compiling Wireshark 1.6.0 with 
Visual Studio 2005 for Win32. Some dissectors have assignments from 64 to 32 
bit, what will issue a warning C4244 by the compiler. Since the -WX 
parameter is passed to the compiler, the compilation fails. The warning 
level /W3 will not suppress the warning C4244 but /W2 would do.

example: packet-afp.c
function: dissect_spotlight
line: 3999
    toc_offset = (spotlight_ntoh64(tvb, offset) >> 32) * 8 - 8;
where the variable is defines as
    gint toc_offset;
Compiler output:

packet-afp.c
packet-afp.c(3999) : error C2220: warning treated as error - no 'object' 
file generated
packet-afp.c(3999) : warning C4244: '=' : conversion from 'guint64' to 
'gint', possible loss of data

Why did this pass the compilation at wireshark.org?
How do I recompile Wireshark 1.6.0?

This affects also

packet-ieee802154.c(2162) : warning C4244: 'return' : conversion from 
'guint64' to 'guint', possible loss of data

packet-netflow.c(2623) : warning C4244: '=' : conversion from 'guint64' to 
'int', possible loss of data
