  Unix systems.

Issues with strict compilation
  In the previous version (1.9.6) I enabled a strict compilation option by
  default. The compiler was configured to use the -Werror argument. The effect is to
  transform warnings into errors. The compilation would fail instead of just
  displaying a warning.
On my side I had no warnings so I was confident.
  But some build systems use a different set of default compilation arguments.
  For example Arch Linux or openSUSE Tumbleweed use the argument -flto=auto to
  perform some link-time optimizer.
  This option generated 3 warnings. The warnings are minor but since the
  compilation used -Werror they were treated as errors and the compilation
  failed.
  Sorry for generating the problem. Thanks to Axel Braun and frederik for
  reporting the failure.
