CVS commit: src/lib/libc/stdlib

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

Module Name:    src
Committed By:   tron
Date:           Sat Sep 25 18:11:40 UTC 2010

Modified Files:
        src/lib/libc/stdlib: getenv.c local.h setenv.c unsetenv.c

Log Message:
Remember memory used by allocated environment variables instead of
using a bitmap. This deals with the case where a variable is first
set via setenv(3) or putenv(3), then overwritten by changing
"environ" directory and afterwards overwritten with setenv(3) again.

This stops "zsh" from crashing under NetBSD-current.

Code reviewed by Christos Zoulas.
