I'm seeing
+UNRESOLVED: g++.dg/cpp2a/concepts-lambda3.C -std=c++11 compilation failed to
produce executable
+UNRESOLVED: g++.dg/cpp2a/concepts-lambda3.C -std=c++14 compilation failed to
produce executable
+UNRESOLVED: g++.dg/cpp2a/concepts-lambda3.C -std=c++17 compilation failed to
produce executable
+UNRESOLVED: g++.dg/cpp2a/concepts-lambda3.C -std=c++98 compilation failed to
produce executable
with this change, and if I test with
GXX_TESTSUITE_STDS=98,11,14,17,20,2b make check-g++ -k
RUNTESTFLAGS="--target_board=unix\{-m32,-m64,-m64/-fconcepts\}
dg.exp=concepts-lambda3.C"
I see even FAILs for the -fconcepts case, so apparently even -std=c++17
-fconcepts isn't enough to make it compile without errors.
The following patch will expect errors for all of c++17_down and will
make the test dg-do compile for that case too, such that the UNRESOLVED
stuff is gone.
Ok for trunk?

* g++.dg/cpp2a/concepts-lambda3.C: Use dg-do run only for c++20,
for c++17_down dg-do compile. Expect dg-excess-errors for c++17_down
rather than ! concepts.
