Hi!

For my recent build trouble of lang/ghc98 that only I can see but pho@
can't[1], upstream has suggested it might be a problem with AVX512
support[2] in NetBSD. (My CPU supports AVX512, pho's doesn't.)

I'll give their suggestion (using -D__STDC_NO_ATOMICS__) a try, but
does anyone know the actual state of AVX512 support on NetBSD?
 Thomas
