[Winpcap-users] Updating BPF compiler

Uhm, recompiling wpcap.dll with the updated version of the libpcap source 
files is not so straightforward. Basically, there are two main problems:

1. the libpcap sources need to be manually patched to include the remote 
support (remote support is not available in the vanilla libpcap sources 
available on www.tcpdump.org). It's possible to avoid patching the files, 
and use a specific wpcap.dll build configuration for this, the "Wpcap 
debug"/"Wpcap release" ones.

2. You need to generate the parser/scanner source files out of the 
flex/bison .l and .y files. In order to do that, you need to have cygwin 
installed and perform an initial compilation of wpcap.dll with cygwin (or at 
least flex/bison, I usually recompile the whole wpcap.dll under cygwin to 
generate those files). In particular, you need to cd to winpcap/wpcap/PRJ 
and type "make -f GNUMakefile".

I know, recompiling wpcap.dll is a pain in the neck...

Have a nice day
