thresholds... (as I don't get "appropriate" thresholds on Linux, and only
rarely on the MacOS X box I have access to).
Ok, did so.
You can now install the spkg with `ZN_POLY_FAKE_THRESHOLDS` set to
something non-empty to set all `mul_fft_thresh`s to 1, [comment:22 as I
previously did to provoke failures].
(Even) with this, the "quick" test suite (still) passes for me now.
Further changes for debugging: Failures in `test_nuss_mul()` now get
reported, and the test suite doesn't exit on the first failure, but
continues testing. (Especially `test_nuss_mul()` now performs all tests
regardless of failures.)
Feel free to change `patches/conditionally_fake_mul_fft_threshs.patch` to
fake other tuning parameters as well; as the name says, I'm only changing
`tuning_info[2..64].mul_fft_thresh` since doing so previously triggered
failures for me.
