Description: ------------ As currently all integers are 32 bits on 32 bits processor, even when php is compiled with Large File Support, all the functions that use integer instead of a right format (stat, filesize, ftell, etc...) don't report the right size when a file is > 4GB. The attached patch solve the issue by using doubles instead of int when a size overflow 32 bits (so as IEEE754 specifies, we have 53 bits of real, integer, value in a double). Unlike Wes patch posted earlier, that didn't work, I've modified all the code that still used size_t to use off_t, modifying the extensions too, memory mapping (that had a bug as it previously failed when offset used, BTW), etc... It works when applyied to released 5.3.0 with patch -p1.
