Just a heads-up, some of these seem to have been compiled with a recent
gcc which might not be what was intended?:

$ strings -fa curve25519-*.o | grep -i gcc
curve25519-3.11.10.o: GCC: (GNU) 4.9.4
curve25519-3.12.74.o: GCC: (Gentoo 11.2.0 p1) 11.2.0
curve25519-3.14.79.o: GCC: (Gentoo 11.2.0 p1) 11.2.0
curve25519-3.15.10.o: GCC: (GNU) 4.9.4
curve25519-3.16.85.o: GCC: (Gentoo 11.2.0 p1) 11.2.0
curve25519-3.17.8.o: GCC: (GNU) 5.5.0
curve25519-3.19.8.o: GCC: (GNU) 5.5.0
curve25519-4.0.9.o: GCC: (GNU) 5.5.0
curve25519-4.5.7.o: GCC: (GNU) 6.5.0
curve25519-4.6.7.o: GCC: (GNU) 6.5.0
curve25519-4.7.10.o: GCC: (GNU) 6.5.0
curve25519-4.8.17.o: GCC: (GNU) 6.5.0

Anyhow, now I'm able to reproduce it myself. Was a PEBCAK config failure.

I'll look into it and work on a fix!

Thanks,
Mathias
