I've tested it with mingw 3.4.2, and here are no problems
finding getaddrinfo:
-- Looking for getaddrinfo
-- Looking for getaddrinfo - found

To test just for getaddrinfo:
(I think you know all the steps, I just wanna be sure)

1. rm CMakeCache.txt
2. cmake -G"MinGW Makefiles" ../kdelibs/win
3. make
4. make install
5. rm CMakeCache.txt
6. cmake -G"MinGW Makefiles" ../kdelibs

now there is a config.h in there folder, delete the line below
//Have symbol getaddrinfo
and run 6. again, so you can test on getaddrinfo only.


The detecting of getaddrinfo should be independent of _WIN32_WINNT and WINVER,
because it is defined in ws2tcpip.h (the version of your mingw installation)
and there are now (at least here) #ifdefs.
