But maybe the better way would be to implement inet_ntop and inet_pton on Windows, or check the licence if one can take it from plibc.
For now one could maybe also just drop the change "Fix IPv6 for WinXP" from this pull request, if this is possible. Unfortunately there are two files changed in this commit: civetweb.c and mod_lua.inl. The changes in mod_lua.inl should be beneficial for all users (WindowsXP, 7, 8, .. Linux, ..), while I had to do the changes in civetweb.c only to test on WinXP.
Don't know if/how this can be done with github?
