Comment (by kelson):

 Some additional info from MediaWiki developer Brion, posted in the
 comments at my writeup:

   This is the breaking change:

   {{{
 -       @header("HTTP/1.1 $header $text");
 -       @header("Status: $header $text");
 +               if ( substr(php_sapi_name(), 0, 3) == 'cgi' )
 +                       @header("HTTP/1.1 $header $text");
 +               else
 +                       @header("Status: $header $text");
 }}}

   Thus instead of hedging its bets by sending both forms to the server,
 it's only sending one form depending on how PHP's set up.

   If I'm not mistaken, the condition should be reversed: the 'Status'
 pseudoheader should be used only for CGI, while Apache/mod_php and other
 environments want the HTTP/1.x line directly.

   In MediaWiki we use the HTTP/1.x form pretty exclusively, actually, and
 it's fine with my lighttpd/FastCGI test box as well as our production
 apache/mod_php boxes... I'm not entirely sure what it __does__ break with.
