That's the same header :-)
I think it should probably be the same as
25_algorithms/headers/algorithm/algorithm_parallel_mode.cc i.e.
// { dg-require-parallel-mode "" }
// { dg-options "-D_GLIBCXX_PARALLEL -fopenmp" { target *-*-* } }
(Although that will mean it almost never gets tested, as nobody runs make
check-parallel routinely ... not that it really matters, as nobody uses
parallel mode either, and it will be deprecated soon).

Probably because it was easier that way. They only depend on omp.h if you
explicitly request it by defining _GLIBCXX_PARALLEL, and if you do that without
libgomp that's your fault. The test that does that needs to be fixed.
