** These #defines should enable >2GB file support on Posix if the

** large file support, or if the OS is windows, these should be no-ops.
**
** Ticket #2739: The _LARGEFILE_SOURCE macro must appear before any
** system #includes. Hence, this block of code must be the very first
** code in all source files.
**
** Large file support can be disabled using the -DSQLITE_DISABLE_LFS switch
** on the compiler command line. This is necessary if you are compiling
** on a recent machine (ex: RedHat 7.2) but you want your code to work
** on an older machine (ex: RedHat 6.0). If you compile on RedHat 7.2
** without this option, LFS is enable. But LFS does not exist in the kernel
** in RedHat 6.0, so the code won't work. Hence, for maximum binary
** portability you should omit LFS.
**
** Similar is true for MacOS. LFS is only supported on MacOS 9 and later.
