Comment(by psarge@…):

 According to the Darcs changelog on this file, it was fixed back in 2007
 to work with Perl 5.9+. I expect the limitation is outdated.

   * * Evil Mangler broke under Perl 5.9+ because $* is gone; this fixes
 it.

     Perl 4's special variable $* controls multi-line matching; it's been
     deprecated from Perl 5's inception, and is finally removed in Perl
     versions 5.9 (soon to be 5.10).

     Since GHC depends on Perl 5.6+ anyway, this patch introduces an
     equivalent effect to $* without using that special variable, by
     hooking into Perl's regex parsing process to add the /m flag.

 Wed Jul 11 22:04:49 BST 2007  audreyt at audreyt.org
   * In mangler, lift the multiline-match pragma to toplevel and document
 it better.

 Thu Jul 12 06:43:51 BST 2007  audreyt at audreyt.org
   * Revert the $* patch for earlier Perls as it breaks the build. Sorry.
 :/

 Mon Jul 30 13:22:16 BST 2007  audreyt at audreyt.org
   * * ghc-asm: Finally did away with $* in a way that works with Perl
 5.6~5.10+, by appending /m to all regexes.
