commit 7e71542e8b ("sha1dc: avoid CPP macro collisions", 25-03-2017)
runs t0000-basic.sh just fine.
commit a0103914c2 ("sha1dc: update from upstream", 20-05-2017) fails
when running t0000-basic.sh.
I will look into this more tomorrow (it is late, I need sleep), unless
someone finds the solution overnight, of course.
Adam, you can build using the OPENSSL_SHA1 build variable for now
(if you want to release v2.13.1), or wait for another maint release
I suppose, ... I'll leave that to you! ;-)
ATB,
