Ah, I think it doesn't work to expand AT_CHECK inside a function.
Sorry for overlooking that requirement of yours.

It might be possible to rework _AT_CHECK so that it will work in
such a setup, should mostly be a matter of assigning some values
that are currently held in m4 macros only to shell variables in
AT_SETUP, and then referencing them in _AT_CHECK.  This would
probably enlarge testsuite code a bit, but maybe negligible.
