I am observing the same problem. Though sometimes it links without
warnings. Looks like if you do a clean build, then change file and
build again there are no warnings, but if you change folder and build
then you get lots of warnings.

One more issue related to this one. Rsp files are not always
regenerated, leading to errors if you build from different folders.
Suppose you have a lib foo, and exe foo_test which uses foo. You first
run clean build, from the root of the project. Then you made change to
one of the foo sources, change dir to foo, and run build. In this
scenarion foo.rsp will be regenerated, you'll get foo.lib (though with
pile of warnings) but foo_test builds with old rsp which has paths
relative from project root, not foo.
