C++ does not like the HPyTuple_Pack macro

[mattip]

When trying to run Cython tests on a branch to provide HPy support (see cython/cython#4490), I am seeing errors of the form below.

error: taking address of temporary array
   25 | #define HPyTuple_Pack(ctx, n, ...) (HPyTuple_FromArray(ctx, (HPy[]){ __VA_ARGS__ }, n))
      |                                                                    ^~~~~~~~~~~~~~~
hpy_basic.cpp:6083:12: note: in expansion of macro ‘HPyTuple_Pack’
 6083 |     args = HPyTuple_Pack(ctx, 1, cleanup_func);

The problem is reproducible in the tests by using a c++ compiler:

$ (cd test; CC=g++ python -m pytest -k test_hpytuple.py -vv -x --compiler-v -k test_Pack)

AFAIK, this issue is resolved (see referenced PR). I'm closing it.
