// System-specific #define, typedefs, corrections, etc, go here.  This

// file will come before all others.

// 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.
