The reason we haven't moved to _GET in PhpWiki is just exactly
the autoglobal semantics.  Since you'd have to 

  global $_GET;

anyway, might was well do

  $_GET = &$GLOBALS['HTTP_GET_VARS'];

(or just use HTTP_GET_VARS.)  It makes it explicit that we're not
using a real (autoglobal) $_GET.

As far as implementing replacement functions, a compat.php
is a fine idea.  (We already do define functions like this,
when they're needed, but their definitions are scattered
all over the place.  Grep for 'function_exists'.)

It's probably a good idea to normalize some of the names,
too.  E.g. we have isa() instead of is_a() for historical
reasons (we invented it before PHP did, I think).
