Hi there,
I have a Linux machine (OpenSuSE 13.1) and I use GNU Make 3.82. According to the instructions, I cloned the following repository by running
git clone git://pike-git.lysator.liu.se/pike.git
so I am not sure whether it is a pre-release or stable one. Another thing is that I use rather older version of autoconf i.e. 2.13 because newer versions of autoconf are not backward compatible. I am not sure if it can be the source of the problem. I downloaded the source code of Pike and it compiled successfully. The error comes up when I clone the git repository.
