See https://stackoverflow.com/questions/62962839/stdaligned-alloc-missing-from-visual-studio-2019 for a possible reason for this, and suggested solution of using macros to switch between the implementations.
Apparently this isn't available on MacOS either. See: https://gitlab.com/gromacs/gromacs/-/issues/3968
