Hi Ravi,

I definitely want to fix this particular issue for 11.3.

Right, the first step would be for a WSL user to figure out what's
wrong with builds on the WSL and show us how to fix it; I heard
through the grapevine that if you try it, initdb doesn't work (it must
be something pretty subtle in the configure phase or something like
that, since the Ubuntu .deb apparently works, except for the issue
reported in this thread). Then, confirm that they're happy with
whatever patch we come up with. Then if someone wants to make sure we
don't accidentally break it in future, yeah, a build farm animal would
help a lot.

Here's a starter patch that shows one of the approaches discussed. It
gets WSL users to a better place than they were before, by suppressing
further warnings after the first one.
