+Pform expansion should work in `exec` but also in `build`:
+
+  $ cat > dune-project << EOF
+  > (lang dune 3.10)
+  > (package (name public))
+  > EOF
+  $ cat > dune << EOF
+  > (executable (public_name public) (modules Public))
+  > (executable (name private) (modules Private))
+  > (env
+  >   (_ (binaries (private.exe as priv))))
+  > EOF
+
+The executables in question just display what they are:
+
+  $ cat > public.ml << EOF
+  > let () = print_endline "Public"
+  > EOF
+  $ cat > private.ml << EOF
+  > let () = print_endline "Private"
+  > EOF
+
+We also have a subfolder `foo`
+
+  $ mkdir foo
+  $ cat > foo/dune << EOF
+  > (executable (public_name blah))
+  > (env
+  >   (_ (binaries (blah.exe as foo))))
+  > EOF
+  $ cat > foo/blah.ml << EOF
+  > let () = print_endline "Blah"
+  > EOF
+
+Making Dune build the executables should work without error messages:
+
+  $ dune build %{bin:public}
+  Error: File unavailable:
+  $TESTCASE_ROOT/../install/default/bin/public
+  [1]
+  $ ls _build/default/public.exe
+  _build/default/public.exe
+
+Building the private executable should also work.
+
+  $ dune build %{bin:private}
+  File "command line", line 1, characters 0-14:
+  Error: Program private not found in the tree or in PATH
+   (context: default)
+  [1]
+  $ ls _build/default/private.exe > /dev/null 2>&1 || return 1
+  [1]
+
+Building the private executable via the env alias should work too:
+
+  $ dune build %{bin:priv}
+
+  $ (cd foo && dune build --root .. %{bin:priv}) # should work
+  Entering directory '..'
+  Leaving directory '..'
+  $ dune build %{bin:foo} # doesn't work because foo is underneath us
+  File "command line", line 1, characters 0-10:
+  Error: Program foo not found in the tree or in PATH
+   (context: default)
+  [1]
+  $ (cd foo && dune build --root .. %{bin:foo}) # should work
+  Entering directory '..'
+  File "command line", line 1, characters 0-10:
+  Error: Program foo not found in the tree or in PATH
+   (context: default)
+  Leaving directory '..'
