This is a 0.3.5 backport of #40275 (closed).
While trying to resolve our CI issues, the Windows build broke with an unused function error:
src/test/test_switch_id.c:37:1: error: ‘unprivileged_port_range_start’ defined but not used [-Werror=unused-function]
We solve this by moving the #if !defined(_WIN32) test above the
unprivileged_port_range_start() function defintion such that it is
included in its body.
This is an unreviewed commit.
