Your build environment is not finding the defines for IPV6 support.

you can search for IN6_ADDR in /usr/include and report which files it is referenced in. Or attach the output of: grep -r IN6_ADDR /usr/include

I am seeing the same thing on a Windows 11 vm with cygwin x64

Here is my output of grep -r IN6_ADDR /usr/include

$ grep -r IN6_ADDR /usr/include

Maybe this is the solution?

I tried this and it seems to have worked.
