 The `LIT64' macro takes as its argument a textual integer literal and
 if necessary ``marks'' the literal as having a 64-bit integer type.
 For example, the GNU C Compiler (`gcc') requires that 64-bit literals be
 appended with the letters `LL' standing for `long long', which is `gcc's
 name for the 64-bit integer type.  Some compilers may allow `LIT64' to be
 defined as the identity macro:  `#define LIT64( a ) a'.
