mingwcompat.c has the following ugly as heck tidbit:
#ifndef WIN32_ONLY_COMPILER
/*
* MingW defines an extern to this struct, but the actual struct isn't present
* in any library. It's trivial enough that we can safely define it
* ourselves.
*/
const struct in6_addr in6addr_any = {{{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0}}};
I think when that was added the problem might just have been
misanalyzed, but due to the auto import magic this probably wasn't
noticed...
