Andrey A. Chernov 2de80aea80 Using putenv() and later direct pointer contents modification it is possibe
to craft environment variables with similar names like that:
a=1
a=2
...
unsetenv("a") should remove them all to make later getenv("a") impossible.
Fix it to do so (this is GNU autoconf test #3 failure too).
