This is an annoying one, see
    https://github.com/diegonehab/luasocket/pull/39

These functions were only introduced in Vista and Win2k8
.
Cross-compiling MinGW on macOS complained in both gcc 7.4 (MinGW 5.0)
and gcc 9.2 (7.0) that inet_pton is missing, but it was only a warning
and the build completed (I'm not sure why).

It's only the native MinGW that errors out if I define the variable
LUASOCKET_INET_PTON since it then apparently sees redefinition of
inet_pton.

It could be that one flavour of MinGW targets older Windows.
I didn't test https://github.com/diegonehab/luasocket/pull/39#issuecomment-18402757,
maybe that could help in some way.

I believe you should be able to get the compilation going if you make
sure that LUASOCKET_INET_PTON doesn't get defined. But once you do
that I'm pretty sure you'll run into troubles with ICU (if you don't,
I would declare it a miracle).
