commit d514e3fc42eb14a1bc5846b27ef89f50ba3a5d48
Author: Ludovic Courtès <ludo@gnu.org>
Date: Tue Oct 11 10:14:26 2016 +0200
Remove 'umask' calls from 'mkdir'.
Fixes <http://bugs.gnu.org/24659>.
* libguile/filesys.c (SCM_DEFINE): Remove calls to 'umask' when MODE is
unbound; instead, use 0777 as the mode. Update docstring to clarify
this.
