I see something similar but different (since 2019); no sources are
recompiled, but everything is linked again, which in my builds is slow.

Assuming you are seeing the same thing, if you keep repeating the same
build, it eventually finishes. If you look in *.bexch, after each build
you will see one more gpr hash added; I gather they should all be added
the first time. So the number of builds needed is the number of *.gpr
you 'with', transitively. After that, each source code change only
requires one build; changes to *.gpr (and some other things?) reset all
the gpr hashes.

I have not reported this to AdaCore; I don't have access to a support
contract for Windows. It would make sense to report it to the community
channel.
