Hi, We are upgrating from perl 5.8.3 on 32bit a platform to 5.8.8 on a 64bit platform. We have some custom XS modules we have written. But I am noticing a difference in the behaviour of the -I flag.

In perl 5.8.8 running
  PERL5LIB=DIR perl -e 'print join("\n",grep(/DIR/,@INC))."\n"'
gives

  DIR/x86_64-linux-thread-multi
  DIR
[download]

But running
  perl -IDIR -e 'print join("\n",grep(/DIR/,@INC))."\n"'
only gives
  DIR

In perl 5.8.3 both commands give the same output. i.e. The -I flag in perl 5.8.3 automatically includes the architecture specific subdirectory, but it does not in perl 5.8.8.

So is this a deliberate change in the behaviour of the -I flag (I couldn't find anything in perldelta) or is there and issue with my perl 5.8.8 setup and/or config.
