__HALT_COMPILER(); patch to be MFB

Hi,

The fix recently incorporated in PHP 5.2.2 for __HALT_COMPILER(); needs
to be MFB. Until today, I didn't have the time to get it working, but
attached is the patch. It is also available at
http://chiaraquartet.net/halt_compiler_php6.patch.txt

P.S. don't prepend www. or you'll get redirected to the chiara quartet
website, which although pretty cool looking, has no patches to HEAD
anywhere to be found.
