CVS commit: src/lib/libc/stdlib

["Matthias Scheler" <tron%netbsd.org@localhost>]

Module Name:    src
Committed By:   tron
Date:           Mon Sep  9 10:21:28 UTC 2013

Modified Files:
        src/lib/libc/stdlib: _env.c

Log Message:
Don't scrub the environment unless we are going to change it. This should
prevent crashes in applications which carefully and manually construct
a temporary environment and later restore the original environment
like Emacs 24.

Problem reported by Thomas Klausner on "pkgsrc-users" mailing list.
