Subject: Remove dead code related to the Atari ST port of perl 4.0 patchlevel 19
X-Git-Tag: upstream/5.20.0~5993
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c458fae0a6159ea505d310a91a4ffcf379153a2;p=platform%2Fupstream%2Fperl.git

Remove dead code related to the Atari ST port of perl 4.0 patchlevel 19

The subdirectory containing the port specific files was purged when 5.000
was released, but changes made to other files were not removed.
