ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Wed May 31 13:07:04 2017 +0300| [4d444d04c1e19cd02ac836d411433906a9f32613] | committer: Martin Storsjö

configure: Default to _WIN32_WINNT=0x0502 (XP) as minimum, for legacy mingw

This makes the getaddrinfo functions visible, which aren't normally
by default on legacy mingw.

We already force __MSVCRT_VERSION__ to an XP version.
