Yeah, sorry, I was expecting google/oss-fuzz#5920 to be merged the same day as I integrated support for Schnorr in Cryptofuzz.

If you think the review process of that PR is going to take several more days, I can comment out Schnorr functions in Cryptofuzz, so that there won't be build errors in the meantime.

[maflcko]

No worries. A failing build for a few days is no big deal.
