Achieving 64-bit integers on 32-bit platforms

Hi Folks This 32-bit limitation is haunting me everywhere I turn. Is it possible with PHP (at compile-time if need be) to make it use large (64-bit) integers? I'm asking because I would like to perform operations on large files, and fillesize($filename) is returning an error, even when I use sprintf("%u", filesize($file)) as per the manual for filesize(). I get: Warning: filesize(): Stat failed for FC4-i386-DVD.iso (errno=75 - Value too large for defined data type) Any thoughts/ideas/suggestions? Thanks!
