/* We need large file support. There are two ways to turn it on:
by defining either _LARGEFILE64_SOURCE or _SGI_SOURCE. However,
it does not actually work to define only the former, as then
<sys/stat.h> is invalid: `st_blocks' is defined to be a macro,
but then used as a field name. So, we have to turn on
_SGI_SOURCE. That only works if _POSIX_SOURCE is turned off,
so we have to explicitly turn it off. (Some of the libio C files
explicitly try to turn it on.) _SGI_SOURCE is actually turned on
implicitly via the command-line. */
