From 245608911698adb3472803856019bdd5670b6614 Mon Sep 17 00:00:00 2001

Subject: 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.
* doc/ref/posix.texi (File System): Adjust accordingly.
* NEWS: Mention it.
