This is a bug report for perl from Alan.Burlison@sun.com,
generated with the help of perlbug 1.35 running under perl v5.8.7.

See http://rt.perl.org/rt3/Ticket/Display.html?id=37376 for background to this
bug.

Defining the PERL_USE_SAFE_PUTENV macro (to work around #37376) breaks the perl
testsuite, specifically tests 12 and 13 in run/runenv.t.  These are testing the
functionality of the PERLLIB environment variable.  Normally PERLLIB is only
used if PERL5LIB is not set, with the PERL_USE_SAFE_PUTENV macro defined it
appears that PERLLLIB is being ignored even when PERL5LIB is not set.
