Hello, we would like to request for some assistance with an issue with File::Temp that we've experienced since installing a new module: https://metacpan.org/pod/Net::Amazon::S3#new

After installation of the module & its dependencies, we had received errors from Temp::File stating: 

Your vendor has not defined Fcntl macro O_NOINHERIT, used at /usr/shar
+e/perl5/File/Temp.pm line 247.
Your vendor has not defined Fcntl macro O_EXLOCK, used at /usr/share/p
+erl5/File/Temp.pm line 256.    
Your vendor has not defined Fcntl macro O_TEMPORARY, used at /usr/shar
+e/perl5/File/Temp.pm line 277.

+erl5/File/Temp.pm line 255.

Upon checking File::Temp these are the lines that are apparently causing issues

 
my $OPENFLAGS = O_CREAT | O_EXCL | O_RDWR;
my $LOCKFLAG;

unless ($^O eq 'MacOS') {
  for my $oflag (qw/ NOFOLLOW BINARY LARGEFILE NOINHERIT /) {
    my ($bit, $func) = (0, "Fcntl::O_" . $oflag);
    no strict 'refs';
    $OPENFLAGS |= $bit if eval {
      # Make sure that redefined die handlers do not cause problems
      # e.g. CGI::Carp
      local $SIG{__DIE__} = sub {};
      local $SIG{__WARN__} = sub {};     
      $bit = &$func();
      1;
    };
  }
  # Special case O_EXLOCK
  $LOCKFLAG = eval {
    local $SIG{__DIE__} = sub {};
    local $SIG{__WARN__} = sub {};
    &Fcntl::O_EXLOCK();
  };
}

we've tried applying the fix mentioned here, but it did not work.

https://bugzilla.mozilla.org/show_bug.cgi?id=171674 https://bugzilla.mozilla.org/show_bug.cgi?id=179171

For reference heres the code after applying the fix: 

 $OPENFLAGS |= $bit if eval {
      # Make sure that redefined die handlers do not cause problems
      # e.g. CGI::Carp
      local $SIG{__DIE__} = sub {};
      local $SIG{__WARN__} = sub {};
      local *CORE::GLOBAL::die = sub {};
      $bit = &$func();
      1;
    };

At this point we are completely lost, is there anything else we can try to remedy the issue? Thanks in advance.
