Thanks for your replies and corrections, and apologies for the confusing version I mentioned.

For this commit, PostgreSQL was successfully built with msvc on both x86 and amd64.

Glad my report was helpful.

I've just pushed that patch to master only.

I noticed your report mentioned that this was for version 15.3. I
assumed this was a mistake as I didn't see any usage of the bit
scanning functions in v15. Commit 677319746 [1] introduced these,
which is new to v16.

Many thanks for reporting this!

David
