civodul pushed a commit to branch stable-2.0
in repository guile.

commit 7043b7ff643c3ada6bf9d51578cb720b6fc4c83b
Author: Ludovic Courtès <l...@gnu.org>
Date:   Tue Oct 11 10:57:43 2016 +0200

    Treat 'SIG_IGN' as a pointer.
    
    * libguile/posix.c (scm_system_star): Cast 'SIG_IGN' to
    'scm_t_uintptr_t' and use 'scm_from_uintptr_t'.  This fixes an
    'int-conversion' warning with GCC 6.2.
