I checked, it does not fix that.
ICC fails the C11 test (fine, as it should, I believe):
--snip--
test_cflags_cc -std=c11 __STDC_VERSION__ >= 201112L
check_cc -std=c11
BEGIN /tmp/ffconf.6i1t5Drn.c

2 #if !(__STDC_VERSION__ >= 201112L)
3 #error "unsatisfied condition: __STDC_VERSION__ >= 201112L"
4 #endif
END /tmp/ffconf.6i1t5Drn.c

but still passes the builtin-stdatomic test:
