Max file size in fopen()

Hello,

I need to open a file with more than 2GB but the following error occurs:

failed to open stream: Value too large for defined data type in
/srv/www/sandboxes/dev02/test.php on line 2

I'm running this php in a 32 bits system.

Googling I found that with the option
"CFLAGS="-D_FILE_OFFSET_BITS=64""  the problem can be solved.

Will I have this issue in a 64 bits System?

Is there some recognized solution for this issue?

Thanks.
