-** 2.5.1 so that we can use the same binaries on both Solaris 2.5.1 and
-** 2.6.  At run time, we detect whether 64-bit file I/O is available by
-** looking up the 64-bit file function symbols in libc.  At build time,
-** we need to define the 64-bit file I/O datatypes that are compatible
-** with their definitions on Solaris 2.6.
