error compiling libcurve

[eyalb39]

I followed the instructions, however it fails for me on the the checking stage.
My environment is: gcc (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609
The error seem a bit trivial related to byte_/const byte_, but I'd rather don't touch as I'm not familiar with the module internals.
I copy from the relevant part of the checks, the error I get is:

configure: ENABLE_CURVE_SELFTEST defined

checking for perror... yes
