I've committed the patch on our sources.
Actually such source file is part of the libpcap official sources, you can see the commit here
http://cvs.tcpdump.org/cgi-bin/cvsweb/libpcap/Win32/Src/gai_strerror.c
Thanks for the bug report!
Have a nice day

Subject: [Winpcap-users] Patch - Problems compiling Winpcap 4.0.1 with MinGW
Hi,
I am trying to compile some libraries (Winpcap 4.0.1/ libnet and others) under MinGW (not the one included in Cygwin, but the one at http://www.mingw.org/).
Here is my environment:
a.. Windows XP pro, 32bits
b.. gcc-core-3.4.5-20060117-1.tar.gz
c.. gcc-g++-3.4.5-20060117-1.tar.gz
d.. gcc-objc-3.4.5-20060117-1.tar.gz
e.. mingw-runtime-3.13.tar.gz
f.. mingw32-make-3.81-2.tar.gz
g.. w32api-3.10.tar.gz
I get the following error:

make: *** [../libpcap/Win32/Src/gai_strerror.o] Error 1
Searching in the mailing list archives, i have found the possible cause of this issue:
http://www.winpcap.org/pipermail/winpcap-users/2005-December/000575.html
A patch seems to be applied to add the gai_strerrorA function that was missing. But in my environment, i have this function already defined in ws2tcpip.h. See the attachment. So simply adding a #ifndef gai_strerror seems to solve the issue.
Here is the patch:
