I'm seeing:

    FAIL: g++.dg/cilk-plus/CK/pr66326.cc  -O1 -fcilkplus (test for excess errors)
    UNRESOLVED: g++.dg/cilk-plus/CK/pr66326.cc  -O1 -fcilkplus compilation failed to produce executable
    FAIL: g++.dg/cilk-plus/CK/pr66326.cc  -O3 -fcilkplus (test for excess errors)
    UNRESOLVED: g++.dg/cilk-plus/CK/pr66326.cc  -O3 -fcilkplus compilation failed to produce executable
    FAIL: g++.dg/cilk-plus/CK/pr66326.cc  -g -O2 -fcilkplus (test for excess errors)
    UNRESOLVED: g++.dg/cilk-plus/CK/pr66326.cc  -g -O2 -fcilkplus compilation failed to produce executable
    FAIL: g++.dg/cilk-plus/CK/pr66326.cc  -g -fcilkplus (test for excess errors)
    UNRESOLVED: g++.dg/cilk-plus/CK/pr66326.cc  -g -fcilkplus compilation failed to produce executable

..., which is because of:

    [...]/gcc/testsuite/g++.dg/cilk-plus/CK/pr66326.cc:5:23: fatal error: cilk/cilk.h: No such file or directory

This is the only test case trying to include that file:

    $ git grep --cached -F cilk.h -- gcc/testsuite/
    gcc/testsuite/g++.dg/cilk-plus/CK/pr66326.cc:#include <cilk/cilk.h>

..., so I guess that's not supported?
