# Apple Clang does not ship an OpenMP runtime; install libomp so that

# still cannot discover it the build falls back to serial and the tests
# still pass, but installing libomp keeps the macOS runner on the same
# parallel code path as Linux/Windows whenever possible.

# Diagnose Windows DLL-load failures: first run said vcomp140 is
# resolvable via ctypes, so the problem is deeper in the chain. Use
# pefile to dump the DLL-level import table of every built .pyd, then
# probe each .pyd with ctypes.WinDLL (which only exercises the Windows
# loader — PyInit never runs, so a WinDLL failure means Windows could
# not resolve a direct DLL import, whereas a WinDLL success + Python
# import failure means the Cython cimport chain in PyInit is what
# fails).
