Starting with go1.19, the Go runtime on Windows now supports the `netgo` build-
flag to use a native Go DNS resolver. Prior to that version, the build-flag
only had an effect on non-Windows platforms. When using the `netgo` build-flag,
the Windows's host resolver is not used, and as a result, custom entries in
`etc/hosts` are ignored, which is a change in behavior from binaries compiled
with older versions of the Go runtime.
From the go1.19 release notes: https://go.dev/doc/go1.19#net
> Resolver.PreferGo is now implemented on Windows and Plan 9. It previously
> only worked on Unix platforms. Combined with Dialer.Resolver and Resolver.Dial,
> it's now possible to write portable programs and be in control of all DNS name
> lookups when dialing.
>
> The net package now has initial support for the netgo build tag on Windows.
> When used, the package uses the Go DNS client (as used by Resolver.PreferGo)
> instead of asking Windows for DNS results. The upstream DNS server it discovers
> from Windows may not yet be correct with complex system network configurations,
> however.
Our Windows binaries are compiled with the "static" (`make/binary-daemon`)
script, which has the `netgo` option set by default. This patch unsets the
`netgo` option when cross-compiling for Windows.
