Subject: [PATCH] PR libstdc++/88204 disable std::complex<long double> tests
The IBM128 long double format isn't foldable in constant expressions, so
conditionally skip the std::complex<long double> cases when they'll
fail.
PR libstdc++/88204
* testsuite/26_numerics/complex/operators/more_constexpr.cc: Do not
test std::complex<long double> if long double format is IBM128.
* testsuite/26_numerics/complex/requirements/more_constexpr.cc:
Likewise.
