Bug #40533 for IPC-System-Simple: Empty $ENV{PATH} results in warnings under Windows.

On Win32 systems, unsetting $ENV{PATH} can result in bizzare results: %ENV = (); capture($command, @args); Use of uninitialized value in split at C:/Perl/site/lib/IPC/System/Simple.pm line 417. "mkdir" failed to start: "The system could not find the environment option that was entered" at C:\example.pl line 93 Both errors are from the _spawn_or_die subroutine. The $^E appears to be completely bogus in this case. Many thanks to Leif Eriksen for reporting this bug.
