Comment (by pggiarrusso):

 > It sounds like we will need separate bindists for OpenBSD 6.0 and 6.1.
 Arg.

 Thanks for the bindist!

 For the record, that seems to be the general rule for OpenBSD—their minor
 releases aren't necessarily compatible, as we learned on the stack side
 :-|. Let me quote
 https://github.com/commercialhaskell/stack/issues/416#issuecomment-282689118:

 > I've asked the OpenBSD mailing list whether static binaries compiled on
 an older release (X) are expected to run on a newer release (X+1, X+2)
 [0]. I've received the following - expected - answer from Sebastien Marie
 [1]:

 change (32 to 64 bits) - see

 kernel (from release X+1), but nothing more could be expected: old things
 are cleaned, so an old binary could be able to run or not (it just depends
 if relying on old API/ABI with kernel - syscalls, struct size...).
