• t/*.t modules don't use Fcntl.pm
  
• using POSIX qw( :fcntl_h ) instead of Fcntl qw( :seek ) for
  backwards compatiblity to 5.00503
  
• added conditional definitions of SEEK* and O* subs as they are not
  defined in perl 5.004
  
• File::Slurp now runs on perl 5.004 and newer (see BUGS section)
  All of the above thanks to Smylers Smylers@stripey.com,
  Piers Kent piers.kent@bbc.co.uk and
  John Alden john.alden@bbc.co.uk
  
• Added pod.t and pod_coverage.t tests. This is to pass all
  the CPANTS tests.
