build fail

[Erik Joelsson]

Hello Sebastian,

Please try running configure with --disable-warnings-as-errors.

When using compiler versions (or OS versions) other than the ones listed 
in doc/building.md it's common to have warnings triggered and we run 
with warnings treated as errors by default.
